Question

The height of a triangle is four times the length of the base. Find the base and height of the triangle if the area is 18 square inches

Answer 1

the base is 3 and the height is 12

Explanation:

Pretend x = the base and the width = 4x

triangle area formula

(1/2)(4x)(x)=18

2x^2=18

x^2=9

x=3

if x=3 then width = 4(3)=12
