Amy made a rectangle blanket that had a perimeter of 28 feet. it was 9 feet long . how wide was it? help to show how to solve

Respuesta :

Perimeter = 2Length + 2Width

Given that Perimeter = 28 feet and length = 9 feet

28 = 2(9) + 2 Width

28 = 18 + 2 Width

2 Width = 28 - 18

2 Width = 10

Width = 10 ÷ 2 

Width = 5

Answer: 5 feet
28 times two

9 times two

Answer
