Answer 1

The surface area is the sum of the area of all the sides.

There are 5 triangle sides with base of 3 and slant height of 11.

There is the pentagon base, which is made up of 5 triangles with base of 3 and height of 3.5

Summing these up give a total surface area of:


`SA = 5((1)/(2))(11)(3) + 5((1)/(2))(3.5)(3) \\ \\ SA = (165)/(2) + (52.5)/(2) = (217.5)/(2) = 108.75`
