Question

If the area of the triangle above is 6, what is its perimeter? @SolomonZelman

Answer 1

A=1/2bh
A=6, h=4, solve for b
6=1/2b(4)
b=3

then, add the three sides together
perimeter=AB+CB+AC
=4+3+5
=12

or you can use Pythagorean theorem to solve for B and then add the three sides together the same way

Answer 2

does that make sense?
