Question

a pool in the sape of a rectangle has a perimeter of 80 feet. the pool is 8 feet less wide than it is long. find the length and width of the pool

Answer 1

Length: 28 ft Width: 12 ft

Explanation:

So to solve this, we know that perimeter means the sum of all the lengths added together. And we can start by dividing 80 by 4.

80 ÷ 4 = 20

And now, the width must be eight feet less than the length, meaning we just subtract eight from the width, and add eight to the length.

20 - 8 = 12

20 + 8 = 28

L = 28

W = 12

And now we can double check:

12+ 28 + 12 + 28 = 80

Have a great day:)
