Answer:
P = 44, A = 81
Step-by-step explanation:
To find the Perimeter, all we need to do is add up the sides, so:
P = 10 + 9 + 10 + 2 + 3 + 3 + 3 + 4 = 44
The numbers 2 and 10 are doubled since there are two sides of the same length. Moreover, the third 3 comes from ( 9 - 4 - 2 ) = 3, to find the last bottom side.
For our area, we can subtract the negative (empty) space from the rectangle. We know that if the polygon was a full rectangle, our area would be 10 × 9. However, we need to subtract the empty space, which is 3 × 3.
So our equation for Area looks like:
A = (10 × 9) - (3 × 3) = 81
