This is an improper polygon. To find the area of this figure we will find the area of the three rectangles inside of the figure. Lets do it:-
Rectangle #1:-
This rectangle is on the left side of the picture. Its from the bottom of the figure to the top.
l = 15m w = 3m
We will use the following formula for all of the rectangles:-
A = wl
A = 3 · 15 A = 45
Rectangle #1:- A = 45m.
Rectangle #2 is the same as rectangle #1 cause it is the same size with the same dimension and it s located all the way to the right of the picture.
Rectangle #2:- A = 45m
Rectangle #3:-
This rectangle is all the way at the top of the pic. It is in between of the other 2 rectangles. To find the length and width of this rectangle we need to use the info on the other sides.
