My perimeter is 30 ft my length is 9 ft. What is the width

Question

My rug has a perimeter of 30 ft, the length is 9 ft. What is the width?

Answer 1

Perimeter is equal to 2L + 2W.

If P = 30 and L = 9, we have

2(9) + 2W = 90 or 18 + 2w = 90

Let's subtract 18 from the 90 and get that 2w = 72.

Divide by 2 and get w=36

So the width is 36
