What is the area of this polygon?

Enter your answer in this box.

60

Step by step explanation:

First we need to split the polygon into two parts to make it easier to calculate. These two parts are a rectangle and a triangle.

Next- to calculate the area of the square, multiply its length and width—6*7-(42).

Then- to find the area of the triangle, multiply it’s base (6) and it’s height (3). Then divide by two to get 9. (18/2)

Add these up (42+9) and we get an area of 51.

List of formulas-

Rectangle: Bh (base times hight)— equivalent to length times width.

Triangle: 1/2Bh (1/2 base times hight)
