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 77=49, and the area of the square is 49 square centimeters.
Then, you find the area of the triangle. The formula is 1/2bh. 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 1/27*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!
