Norwegian Flag Dimensions A Mathematical Problem

Hey there, math enthusiasts! Ever wondered about the mathematical secrets hidden within the iconic Norwegian flag? Well, buckle up because we're about to embark on a fascinating journey to unravel its dimensions using the power of equations. We will solve the problem: The perimeter of the Norwegian flag is 190 inches. What are the dimensions of the flag? Write and solve an equation to answer the question.

Decoding the Norwegian Flag's Perimeter Puzzle

In this mathematical quest, we're given a crucial piece of information: the perimeter of the Norwegian flag is a whopping 190 inches. Our mission, should we choose to accept it (and we definitely do!), is to decipher the flag's length and width. To do this, we'll transform this word problem into a tangible equation, a mathematical decoder if you will, and then solve it to reveal the flag's hidden dimensions. So, grab your thinking caps, and let's dive into the fascinating world where geometry meets the Norwegian spirit!

Cracking the Code Setting Up the Equation

Now, before we jump into the nitty-gritty, let's refresh our understanding of the Norwegian flag's design. It's a beautiful tapestry of red, white, and blue, featuring a Nordic cross that extends to the edges of the flag. The key here is the proportional relationship between the flag's width and length, which is elegantly expressed as a ratio. If we let 'y' represent the width of the flag, then the length can be represented as 11/8 of the width, or (11/8)y. This ratio is the cornerstone of our equation, the secret ingredient that will unlock the flag's dimensions.

But wait, there's more! We also need to remember the fundamental formula for the perimeter of a rectangle: Perimeter = 2(length + width). This formula is our trusty guide, the map that will lead us to our treasure. By substituting our expressions for length and width into this formula, we create a powerful equation that encapsulates the essence of the problem: 190 = 2(y + (11/8)y). This, my friends, is our mathematical masterpiece, the key to unlocking the flag's dimensions. It looks scary at first, but trust me, we got this!

Unlocking the Dimensions Solving the Equation

With our equation in hand, we're ready to roll up our sleeves and get our hands dirty with some algebraic magic. The equation, 190 = 2(y + (11/8)y), might seem a bit intimidating at first glance, but fear not! We'll break it down step by step, using our trusty mathematical tools to simplify and conquer. The first step is to simplify the expression inside the parentheses. We need to combine the 'y' terms, but they're not quite in the same form yet. We have a 'y' and an '(11/8)y', which is like saying we have one whole 'y' and then eleven-eighths of a 'y'. To combine them, we need a common denominator, which in this case is 8. So, we rewrite 'y' as '8/8 y'.

Now, we can add them together! (8/8)y + (11/8)y = (19/8)y. Our equation now looks a little cleaner: 190 = 2((19/8)y). Next, we can get rid of those parentheses by multiplying the 2 by the (19/8)y. This gives us 190 = (38/8)y. We can simplify the fraction 38/8 by dividing both the numerator and the denominator by 2, resulting in 19/4. So, our equation becomes 190 = (19/4)y. We're getting closer! To isolate 'y' and finally reveal the flag's width, we need to get rid of the (19/4) that's multiplying it. We do this by performing the opposite operation: multiplying both sides of the equation by the reciprocal of (19/4), which is (4/19).

So, we multiply both sides by (4/19): (4/19) * 190 = (4/19) * (19/4)y. On the right side, the (4/19) and (19/4) cancel each other out, leaving us with just 'y'. On the left side, we have (4/19) * 190. We can simplify this by dividing 190 by 19, which gives us 10. So, we have 4 * 10 = y, which means y = 40. Eureka! We've found the width of the flag: 40 inches. But wait, our adventure isn't over yet! We still need to find the length. Remember, we said the length is (11/8)y. Now that we know y = 40, we can simply substitute it into this expression: Length = (11/8) * 40. We can simplify this by dividing 40 by 8, which gives us 5. So, we have Length = 11 * 5, which means Length = 55 inches.

The Grand Reveal Flag's Dimensions Unveiled

Drumroll, please! After our mathematical expedition, we've finally arrived at our destination: the dimensions of the Norwegian flag. The width, represented by our trusty variable 'y', is a respectable 40 inches. And the length, which we calculated using the flag's inherent proportions, stretches out to a proud 55 inches. So there you have it, guys! We've successfully deciphered the mathematical code hidden within the Norwegian flag's perimeter. We took a word problem, transformed it into an equation, and then, with a little algebraic wizardry, we solved it to reveal the flag's dimensions. Isn't math just amazing?
