20) A triangle has an area of 110 square inches and a base of 15 inches. Which answer best pinpoints the height? 

1. 14 inches
2. 18 inches
3. 18.66 inches
4. 14.66 inches

To determine the area of a triangle, use the equation

A=¹/₂bh (or base times height)

The problem gives you the area as being 110 square inches. Plug that in for A.

Next, plug in 15 inches for base (also given) and solve for h.
