The rectangle shown is composed of smaller equally-sized squares. The shaded section has an area of 3/16 square inches. Use a unit rate to determine the area of the larger rectangle.

Area of larger rectangle = 1½ = 1.5 in²

Step-by-step explanation:

The section consists of 3 small squares that has an area = .

Area of 3 small squares =

Area of 1 small square = ÷ 3

=

=

The larger rectangle has 24 small squares of equal sizes

Area of larger rectangle = area of 1 small square * 24

=

Area of larger rectangle = 1½ = 1.5 in²

x/3-10=8

x/3=18

x=48
