Question

The given figure shows a right triangular prism. Find the lateral surface area of the prism.

• A. $240$ $c{m}^2$
• B. $550$ $c{m}^2$
• C. $520$ $c{m}^2$
• D. $480$ $c{m}^2$

Answer 1

The correct option is D $480$ $c{m}^2$

Lateral surface area = Perimeter of the triangular base Height
$=(20+12+16)\times 10$
$=48\times 10$
$=480$ $c{m}^2$
