Question

What is the area of the irregular polygon shown below?

Answer 1

Letter A, the answer is 121.5 square ft.

Answer 2

Explanation:

Area of given figure is combination of area of rectangle and area of Pentagon

Area of rectangle = length x width

= 6 x10

= 60 sq units

Area of pentagon =
`(a p)/(2)` where a = apothem and p = perimeter

Area of pentagon =
`((4.1)X6(5))/(2)`

=61.5 sq units

Area of the given figure = area of rectangle + area of pentagon

= 60 + 61.5

121.5 sq units
