Answer 1

Add one point Seven twice then add and thing after to get twenty one point four

Answer 2

Answer:  21.4 square meters

Work Shown:

A = area of the front triangular face

A = base*height/2

A = 2*1.7/2

A = 1.7

L = lateral area

L = (perimeter of the base)*(depth)

L = (2+2+2)*(3)

L = 18

SA = total surface area of a triangular prism

SA = 2*A+L

SA = 2*1.7+18

SA = 21.4 square meters
