Respuesta :

62 in squared

The area of one rectangular side is 2.5x7 = 17.5
There are two of these rectangles so 17.5 x 2 = 35

The bottom rectangle has an area if 3x7=21
The triangles each have an area of (2x3)/2=3

Add up all the areas calculated and you get:
35+21+3+3 = 62 for the surface area

Answer:

the answer is 62 in. 2

Step-by-step explanation:

(the base is the triangle)

base:2*3/2 * 2 = 6
sides: 2.5*7*2 = 35
bottom: 3*7 = 21

base+sides+bottom
= 6+35+21
=62 in. 2
