Question

A wall shown in the figure is made up of square bricks of unit length. What is the area of the wall?

• A. 1 sq unit
• B. 3 sq units
• C. 20 sq units
• D. 24 sq units

Answer 1

The correct option is D 24 sq units

Given, side of square brick = 1 unit
$\because$ Area of a square = side x side
$\therefore$ Area of a square brick = 1 x 1
= 1 sq. units

To find the area of the wall, count the number of square bricks in the wall.

By observing the given figure, number of square bricks in the wall is 24.
$\therefore$ Area of the wall = 24 $\times$ Area of each square brick
= 24 sq. units
