PLZ HELPP Which expressions will help you find the surface area of this right triangular prism? Select all that apply.

11 × 3
1/2 × 3 × 5
4 × 11
5 × 11

Select:

11 x 3

4 x 11

5 x 11

Step-by-step explanation:

Notice that the surface area of the prism consists of three rectangles (whose area formula is the product of "length times the width" of each lateral surface), plus the area of two equal right-angle triangles of base 4 and height 3)

Therefore, the formulas we will need to use are:

1) for one of the rectangular faces = 11 x 3

2) for another rectangular face =  5 x 11

3) for the third  rectangular face = 4 x 11

4) for each of the triangular bases =

Therefore only three formula expressions need to be selected from the given list.
