The area of the triangle below is 28.5 square inches. What is the length of the base?
Given the following triangle:
Area = 28.5 square in
Height = 7.5 in
We know the area is 28.5 so to find the base we need to ensure that it equals 28.5 after calculating the area.
[tex]\frac{a\times h}{2}=\frac{7.5\times7.6}{2}=7.5\times7.6=57\div2=28.5[/tex]So the base would be 7.6 inches
