Question

The base of a triangle is 6 cm greater than the height. The area is 20 cm^2. Find the height and length of the base

Answer 1

a = 1/2b*h
20=(x +6)(x)/2
20 = (x^2+6x)/2
40=x^2+6x
40 = (x+3)^2 -9
49=(x+3)^2
7=x+3
x=4
b= 4+6, h = 4.

a=1/2b*h, 10*4/2 = 20.

Answer 2

Or base = 10

Answer 3

height = 4
