Question

Henry want to know how long his patio is . He said the perimeter of his patio is 48 feet . He knows that one side of his patio is 9 feet long . How many feet long are all the sides

Answer 1

Explanation:

Perimeter = 48 feet

2*(length + width) = 48

2*(9 + width ) = 48

Divide both sides by 2.

9 + width = 48/2

9+width = 24

Subtract 9 from both sides.

9+width - 9 = 24 - 9

Width = 15 feet
