Question 645282
Hello, 
Area of a Triangle is equal to (1/2)base*height
so let's plug in what we know: (note: represent base as x)
36=(1/2)(x)(x+1)
Expand:
36=1/2x^2+1/2x
Multiply by 2 and subtract 72:
x^2+x-72=0
Factor this:
(x-8)(x+9)=0
x=8
x=-0
So the base is 8 cm and 
height is 9 cm
Make sense?
