Question

A rectangle has an area of 28 ft2. If the width of the rectangle is 5 ft, what is the length?

Answer 1

Area of a Rectangle = Length x Width
28 ft² = L x 5ft
28 ft² / 5ft = Length
5.6 ft = length.  CHOICE A.

Perimeter of a Rectangle = 2(L + W)
20 ft = 2(L + 4)
20 ft = 2L + 8
20 - 8 = 2L
12 = 2L
12/2 = 2L/2
6 ft= Length  CHOICE A.
