Doubling the base without changing the height would simply double the area.
So the increase is 48 square inches, which means the original triangle is 48 square inches.
48 = (1/2)base(12)
base = 8
The area A of a triangle is given by the formula A=1/2bh If the base of the triangle with height 12 inches is doubled, its area will be increased by 48 square inches. Find the base of the orignial triangle.
