Question

Ms. Fords kitchen is in the shape of a rectangle with a width of 12.25 feet she is buying a wallpaper border to go on all of the kitchen walls she wants to buy 5 extra feet of the border to make sure she has enough she buys 62.5 feet of the border what's the length of her kitchen?

Answer 1

Length of the rectangle = 16.5 feet

Explanation:

Border length bought = 62.5 feet

Including 5 feet extra

Border length needed = 62.5 feet - 5 feet

= 57.5 feet

Border needed = perimeter of the rectangle = 57.5 feet

Width of the rectangle = 12.25 feet

Length of the rectangle = x feet

Perimeter of a rectangle = 2(Length + width)

57.5 =2(x + 12.25)

57.5 = 2x + 24.5

57.5 - 24.5 = 2x

33 = 2x

x = 33/2

x = 16.5 feet

Length of the rectangle = 16.5 feet
