Question

PLEASE HELP ME WITH THIS THANKS

Answer 1

Surface area = 2419.34 square meters

Solution:

The base is a heptagon. It have 7 sides.

Area of base (B) =
`(7)/(2)ar`

`$=(7)/(2)*11*11.42`

Area of base (B) = 439.67 m²

Perimeter of base (P) = Number of sides × side length of base

= 7 × 11

Perimeter of base (P) = 77 m

Distance between bases = 20 m

Surface area of the prism = 2B + PH

= 2 × 439.67 + 77 × 20

= 879.34 + 1540

= 2419.34 m²

Surface area = 2419.34 square meters
