Question

A triangle has a base of 3 feet and an area of 15 square feet. Find the triangle's height

Answer 1

10

Explanation:

A=1/2*b*h

15=1/2*3*h

15=3/2*h

15=3/2h

h=15/(3/2)

h=(15/1)(2/3)

h=30/3

simplify

h=10

Answer 2

10 ft

Explanation:

The formula for the area of a triangle can be used. Put the known values into the formula and solve for the unknown.

A = (1/2)bh

15 = (1/2)(3)h

h = 15/1.5 = 10

The triangle's height is 10 feet.
