The area of the triangle is , A= 1/2 Bh.
We can redraw the triangle this way, for us to be sure which side of the triangle which we have to consider as the base and height. Notice that we have a right triangle.
The base and height of the triangle are 8 feet and 15 feet respectively. Therefore, the area is:
A = 1/2 Bh = 1/2 ( 8 feet) (15 feet) = 60 square feet.
The unit of area is always raised to the second power ( or square units) such as ft^2, square meters, sq.in, etc.
Answer : A = 60 sq. ft.
