QUESTION: 1

In fig., a square of side 5 cm, the area of shaded portion is

Solution:

Area of square having sides 5 cm = 52 = 25 cm2

Area of smaller square having sides 1 cm = 12 = 1 cm2

Then area of 4 squares will be 4 cm2

Area of shaded portion will be =  Area of square having sides 5 cm - area of 4  smaller squares (Unshaded portion)

 Area of shaded portion = 25 cm- 4 cm2

 Area of shaded portion = 21 cm2
