Sample Problem

After Benjamin removed some 2-cm squares from a big rectangle, the following figure is obtained. What is the area of the figure?

The area of the figure is cm2.

Solution

Number of squares = 35

Number of squares removed = 9

Number of squares remaining = 35 – 9 = 26

Area of 1 square = 2 cm × 2 cm = 4 cm2

Area of squares = 26 × 4 = 104 cm2

The area of the figure is 104 cm2
