Question

Can someone help me? Find the surface area of the prism I will give you 14 points to anwser this!

Answer 1

The surface area is 15.

The area formula for a triangle is 1/2bh
The base of the surface is not given but it’s a parallelogram so opposite sides are congruent. The base would be 7 and the height would be 5.

7 x 5 = 30

you then divide it by half


SURFACE AREA = 15
