Let x=height. then base is x+4. plug what we know into the formula for the area of a triangle
A=½bh
16=½*(x+4)*(x)
32=x²+4x
x²+4x-32=0
(x+8)(x-4)=0
so x can be-8 our 4. when we plug-8 in for x we get a negative height. since a triangle cannot have a negative side length we discard-8 and try 4. height=4 and base=8
Answer:
8
Dont mind me if i am wrong!
120×90/100 = 12×9 = 108
