What is the surface area of this figure in square centimeters?

Mashutka [201]

9514 1404 393

Answer:

A. 96

Step-by-step explanation:

The surface area is the sum of the areas of the two triangular bases and the areas of the three rectangular lateral faces.

A = 2(1/2)bh + PH

where b is the base of the triangle, h is its height, P is the perimeter of the triangle, and H is the height of the prism.

A = (3 cm)(4 cm) +(3 +4 +5 cm)(7 cm) = 12 cm² +84 cm²

A = 96 cm²

The surface area of the triangular prism is 96 square cm.
