Question

The perimeter of a rectangular rug is 40 ft. It's length is 12 ft. What is it's width?

Answer 1

Answer:

The answer is 8 ft

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

perimeter = 40 ft

length = 12 ft

Substitute the values into the above formula and solve for the width

That's

40 = 2(12) + 2w

40 = 24 + 2w

2w = 40 - 24

2w = 16

Divide both sides by 2

We have the final answer as

8 ft
