Question

What is the area of the right triangle with lengths of perpendicular sides equal to 2 cm each?

• A. 4 $c{m}^2$
• B. $\sqrt{2}c{m}^2$
• C. 2 $c{m}^2$
• D. 2$\sqrt{2}c{m}^2$

Answer 1

The correct option is C

2 $c{m}^2$

To find the area of the given right-angled triangle, we do not need to find the third side.

We can directly find it by applying the formula $\frac{1}{2}\times Base\times Height$

Base BC = 2 cm

Height AB = 2cm

$\therefore$ The area of the triangle = $\frac{1}{2}\times 2\times 2$ = 2 $c{m}^2$
