ANSWER:
187.5 in^2
STEP-BY-STEP EXPLANATION:
We know that the area of a triangle is equal to the base times the height divided by 2
In the figure we have these values
The base is 3 squares that is 15 inches and the height is 5 squares that is 25 inches since each square measures 5 inches
The area is
[tex]A=\frac{b\cdot h}{2}=\frac{15\cdot25}{2}=\frac{375}{2}=187.5[/tex]
The area of the triangle is 187.5 square inches
