Answer:
The answer is 82 square feet
Step-by-step explanation:
An easy way to do this is to split it into two rectanlges. You can do 10*5 and 8*4 as the dimensions to the two rectangles or you can do 2*4 and 9*8.
I am going to do the first option.
The area of a rectangle is length times width.
Rectangle one can be the one with the dimensions 10 and 5 and the length and width.
Rectangle two can be the one with the dimensions 8 and 4 and the length and width.
Area of rectangle one = 50 feet^2
Area of rectangle two = 32 feet^2
Since we split a large irregular shape into two bits, we must add them together, which results in 82 feet^2.
