Question

Calculate the area of the green-colored portion of the following figure.

• A. 36 sq cm
• B. 24 sq cm
• C. 30 sq cm
• D. 42 sq cm

Answer 1

The correct option is A 36 sq cm


Length of outer rectangle = 8 cm
And breadth of the grey-colored portion = 1 cm

Hence, length of the inner rectangle
= (8 - 1 - 1) cm
= 8 - 2 cm
= 6 cm

Breadth of the inner rectangle
= (8 - 1 - 1) cm
= 8 - 2 cm
= 6 cm

So, the area of the green portion
= side × side
= 6 cm × 6 cm
= 36 sq cm.
