Question

A triangular bandana has an area of 90 square inches. The height of the triangle is 5 5/8 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.

Answer 1

b = 2 · A/h
b = 2 / 1 x 90 / 5 5/8 top times top, bottom times bottom (2 x 90, 1 x 5 5/8)
b = 180 / 5 5/8
b = 32

CHECK ANSWER BY INPUTTING AREA EQUATION AND FILL IN NUMBERS

A =    height x base
