Question

The length of a rectangle is 10, and the width is x - 2. If the area of the rectangle is 80sq cm, find

the dimensions.

Answer 1

Length = 10 cm

Width = 10-2 = 8 cm

Explanation:

Area formula (L)(W)

80 = 10(x-2)

80 = 10x - 20

Add 20 to both side

100 = 10x

x= 10

Length = 10 cm

Width = 10-2 = 8 cm
