what is the formula for finding the area of a triangle?

A = 1/2bh

so you plug in x+4 for b and x for h and set it all equal to 16 and solve for x

still don't know the answer.

can you set up the equation?

Im so lost ... Sorry

you know the area is 16, that is the A so A = 1/2 b h becomes 16 = 1/2 b h now you know b is x+4 and h is x so plug them in the same way

so x equals 8
anonymous
  • anonymous
why does x equal 8? I don't see it
anonymous
  • anonymous
You said A = 1/2 bh so if I SAY 1/2 * 8*4 that equals 16
anonymous
  • anonymous
if x = 8 then what is x+4 ? the equation you need to solve is: 16 = 1/2 (x) (x+4)
