A rectangular Persian carpet has a perimeter of 176 inches. The length of the carpet is 20 inches more than the width. What are the dimensions of the carpet?

Answer :

The dimension of the carpet are 54 inches and 34 inches.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given,

A rectangular Persians carpet has a perimeter of 176 inches.

Now,

The perimeter of a rectangle is;

P =2W + 2L

In this case;

⇒ 176= 2W + 2L

Also, the 2nd sentence says;

⇒ L = W + 20

We can substitute this value of length in the perimeter formula as;

176 = 2W + 2(W+20)

176 = 2W+ 2W + 40

176 = 4W + 40

136 = 4W

34 = W

W = 34

Since, L = W +20

L = 34 + 20

= 54

Thus, The dimensions are 54 inches and 34 inches.

The dimensions of the carpet are 54 inches in length and 34 inches in width. This was determined by setting up and solving the perimeter equation for a rectangle, after which we calculated the length by adding 20 to the width.

To determine the dimensions of a rectangular Persian carpet with a perimeter of 176 inches where the length is 20 inches more than the width, first, let's let the width be represented by w inches. The length will then be w + 20 inches. The perimeter of a rectangle is calculated by adding together twice the width and twice the length (P = 2w + 2l).

The formula with the given values will look like this:
176 = 2w + 2(w + 20)

Simplifying this equation gives us the width and subsequently the length:

176 = 2w + 2w + 40

176 = 4w + 40

136 = 4w

w = 34

So, the width of the carpet is 34 inches. To find the length, we add 20 inches to the width:

Length = w + 20 = 34 + 20 = 54 inches

Therefore, the dimensions of the carpet are 54 inches in length and 34 inches in width.
