Solution

The correct option is A 336
Let the perimeter of the base = P and height = H.

$L a t e r a l s u r f a c e a r e a = p e r i m e t e r o f t h e b a s e \times h e i g h t$

$L a t e r a l s u r f a c e a r e a = P \times H$

$L a t e r a l s u r f a c e a r e a = 28 \times 12$

$L a t e r a l s u r f a c e a r e a = 336 m^{2}$
