You can put this solution on YOUR website! The formula for the area of a triangle (A) is that the area equals one-half times the base of
the triangle (b) times the height of the triangle (h). In equation form this is:
.
.
The problem tells you that the base b of the triangle equals 9 inches and the height h of the triangle
equals 12 inches. Substitute 9 for b and 12 for h in the area formula to get:
.
.
Do the multiplication and division on the right side to get:
.
.
The area of this triangle is 54 square inches. (Don't forget to include the units in your answer
if units are given in the problem.) In this case the units given were inches, so the area is
in units of square inches.
