Question

A triangular pane of glass has a height of 46 inches and an area of 460 square inches. What is the length of the base of the pane?

The length of the base of the pane is ___ inches.

Answer 1

One formula for the area of a triangle is: A = ½·b·h

Since A = 270 and h = 30: 270 = ½·b·30

270 = 15·b

18 = b
