Answer:

17.6ft^2

Step-by-step explanation:

triangular prism surface area = bh + (s1 + s2 + s3)H

where bh=base*height (of triangle)

s1=side 1(of triangle)

s2=side 2(triangle)

s3=side 3(triangle)

h=height(AKA length of rectangle)

so height of the triangles 2 and base=1

2+(1+2+2.2)3

2+(5.2)3

2+15.6=17.6

17.6ft^2
