Question

A rectangle’s area and perimeter have the same numerical value. The length of the rectangle is 10 feet.

Answer 1

Answer:

The width of the rectangle is 2.5 feet

Step-by-step explanation:

Here, we want to calculate the width of the rectangle given its length

Let the area = perimeter = x

Mathematically;

area of rectangle = L * B = 10B

The perimeter of the rectangle = 2(L + B)

Also;

x = 10B

Let’s equate this to the perimeter

x = 10B = 2(L + B)

10B = 2(10 + B)

10B = 20 + 2B

10B -2B = 20

8B = 20

B = 20/8

B = 5/2

B = 2.5
