Question

Calculate the area of the irregular polygon shown below: Image of letter E with height of 12 and width of 10 and inside space of height of 5 and width of 7. All units are in inches.

Answer 1

I think that the figure above represents the information you wrote.
You can divide up the E into pieces and find the area of each piece, and then add all the areas together.
I think it will be faster to find the area of the entire outer rectangle which is 12 in. by 10 in., and then subtract the two 5 in. by 7 in. rectangles.
