Question

Find the surface area of the triangular prism. The base of the prism is an

isosceles triangle.
The surface area is cm Superscript 2.
37 cm
35 cm
47 cm
24 cm

Answer 1

5446cm²

Explanation:

the surface area = the 2 isosceles triangles + the 2 sides + the base

= 2 (24/2 X 35) + 2(37 X 47) + (47 X 24)

= 5446cm²

Answer 2

Answer: 5,446 cm²

Explanation:

First, we will find the area of the two triangle sides.

A = 2 * (
`(bh)/(2)`)

A = bh

A = (35 cm)(24 cm)

A = 840 cm²

Next, we will find the area of the three rectangular sides. We have two that are congruent and a third that is not.

A = 2 * (LW)

A = 2 * ((47 cm)(37 cm))

A = 2 * 1,739 cm²

A = 3,478 cm²

A = LW

A = (24 cm)(47 cm)

A = 1,128 cm²

Lastly, we will add all of these faces together.

840 cm² + 3,478 cm² + 1,128 cm² = 5,446 cm²
