Okay so to find the area you need to find the area of both shapes, then add them to find the final area.

For the square, A=bh
A=(7)(7)
A=49 cm^2

For the triangle, A=1/2bh
A=1/2(3)(7)
A=10.5 cm^2

Add together,

49+10.5 = 59.5 cm^2

I hope that helps!

First, you find the area of the square. You do 7*7=49, and the area of the square is 49 square centimeters.

Then, you find the area of the triangle. The formula is 1/2*b*h. You know that the base is equal to the side of the square, so it is 7, and it tells you that the height is 3. You do 1/2*7*3=10.5, so the area of the triangle is 10.5.

Since you're trying to find out the area of the entire figure, you add the areas of the square and the triangle. 49+10.5=59.5, so the area of the entire figure is 59.5 square centimeters, or choice C.

Sorry for the long answer! Good luck!
