Question

47 cm

Find the surface area of the triangular prism. The base of the
prism is an isosceles triangle.
37 cm
35 cm
24 cm
The surface area is cm².

Answer 1

I'll setup the problem. But I have a question about the car the equal sides of the isosceles triangle. We'll go with 37 cm

Explanation:

you will have to find the areas of the 2 isosceles triangles at either end and the 3 rectangles around the triangles.

Area for the triangles

`A = (1)/(2) bh`

b = base of triangle, I'll guess it's 24cm

h = height (draw a line between the vertex of the equal sdes to the base at a right angle, then use Pythagoras to

find the height)

`</p><p> h = \sqrt{ {37}^(2) - {( (1)/(2)b) }^(2)}`

area for rectangles

37x47 + 24x47 + 37x47

sorry it's a little sloppy (I'm on a cellphone)
