Answer:
Step-by-step explanation:
find the area of every face and the base
area of face 1= 2
area of face 2= 2
area of face 3 = 2
area of base 1= 1.7
7.7 in squared
area of a triangle is the base x height divided by 2
face 1- 2 x 2=4
4/2=2
2x3(theres 3 faces to a triangle) =6
area of base- 2 x 1.7= 3.4
3.2/2=1.7
add the faces and the base together
7.7
