Question

The base of a prism is a quadrilateral of sides 5 cm, 7 cm, 2 cm and 10 cm respectively. If the height of the prism is 50 cm, then find the lateral surface area of the prism.

• A. 1100 $c{m}^2$
• B. 1200 $c{m}^2$
• C. 1300 $c{m}^2$
• D. 1400 $c{m}^2$

Answer 1

The correct option is B 1200 $c{m}^2$

Lateral surface area of a prism = Perimeter of the base $\times$ height

Now, perimeter of the base
$=(5+7+2+10)cm=24cm$

So, lateral surface area $=24\times 50$
$=1200c{m}^2$
