**Anonymous**, Monday, January 17, 2011 at 3:00amLet height is x.

So base=x+8

area of triangle=1/2*b*h

given area=24

so 24=1/2*b*h

2*24=(x+8)*x

48=(x^2+8x)

x^2+8x-48=0

x^2+(12x-4x)-48=0

x^2+12x-4x-48=0

x(x+12)-4(x+12)=0

(x+12)(x-4)=0

x=4,-12

so taking x=4

height=4cm

base=x+8=4+8=12cm
