Question

Find the area of a square clipboard whose side measures 120 cm.

• A. 14400 $c{m}^2$
• B. 144 $c{m}^2$
• C. 1440 $c{m}^2$
• D. 14400 $m^2$

Answer 1

The correct option is A

14400 $c{m}^2$

Area of a square with side length 'a' units is $a^2$.

Let the side of the clipboard be 'a'.

Given, a = 120 cm

$\therefore$ Area of the clipboard = $a^2$ = 120 × 120 = 14400 $c{m}^2$
