Question

A road sign in the shape of a triangle has a base length of 18 inches and a height of 16 inches. what is the area of the road sign

Answer 1

Answer: 144 in^2

Step-by-step explanation:
For this problem, we need to know that the area of a triangle is calculated using one half the base times the height

Area = (1/2) * Base * Height

We are given the base is 18 inches
We are given the height is 16 inches

So we use those values to compute the area.

Area = (1/2) * 18in * 16in
Area = 9in * 16in
Area = 144 in^2
