What is the answer

Question

Henry's patio is in the shape of a rectangle. He drew the given model of his patio. He said the perimeter of the patio is 48 feet. He knows that one side is 9 feet wide. How many feet long are all the sides of his patio?

Answer 1

Hi Gada!

So if the total perimeter is 48 feet, and one side length is 9 ft, then we can turn this into an equation to solve for our unknown (the width).

The formula for perimeter is 2w + 2l = P, so we can substitute in what we know!

2w + (2 x 9) = 48

2w + 18 = 48

2w = 30

w = 15

Hope this helps!!

Answer 2

2*9+2x=48

18+2x=48

2x=30

x=15

y=9
