A triangular bandana has an area of 78 square inches. The height of the triangle is 9 3 4 inches. Enter and solve an equation to find the length of the base of the triangle. Use b to represent the length of the base. An equation to find the length of the base of the triangle is 78= The length of the base of the triangle is inches.

Answer 1

Area of triangle = 1/2 x base x height:

78 = 1/2 x base x 9 3/4

Multiply both sides by 2:

156 = base x 9 3/4

Divide both sides by 9 3/4:

Base = 16 inches
