A rectangular Persian carpet has a perimeter of 216 inches. The length of the carpet is 22 inches more than the width. What are the dimensions of the carpet?

A. 65 inches by 87 inches
B. 97 inches by 119 inches
C. 86 inches by 108 inches
D. 43 inches by 65 inches

Answer :

Final answer:

The width of the carpet is 43 inches and the length is 65 inches.


Explanation:

Let's first assign variables to the dimensions of the carpet. Let x represent the width of the carpet. According to the given information, the length is 22 inches more than the width, so the length can be represented as x + 22.

Now let's use the formula for the perimeter of a rectangle, which is P = 2(l + w). Since we are given the perimeter of the carpet, which is 216 inches, we can plug in the values we just assigned: 216 = 2(x + x + 22).

Simplifying the equation, we have 216 = 2(2x + 22). Distributing the 2 on the right side, we get 216 = 4x + 44. Subtracting 44 from both sides, we have 172 = 4x. Dividing both sides by 4, we find x = 43.

So the width of the carpet is 43 inches, and the length is x + 22, which is 43 + 22 = 65 inches. Therefore, the dimensions of the carpet are 43 inches by 65 inches.
