Answer 1

Answer:

The lateral surface area of the rectangular pyramid is equal to sum of area of 4 lateral triangles.

Here, the base is square, then 4 lateral triangles have equal area.

=> Lateral surface area of this rectangular pyramid:

A = (area of lateral triangle) x 4

  = (12 x 14 x 1/2) x 4 = 336 (ft2)

=> Option C is correct.

Hope this helps!
