What is the value of b in the triangle shown below?

The triangle they are showing is a right triangle...the length is 3b and the width is b...on the inside of the triangle it says 24in^2.

A.–4 in
B.4 in
C.±4 in
D.no solution
Please help I do not know how to do these...if I had to guess it would be B or C...thanks

  1. So the area of a triangle is the following:

    A =( B x H) / 2
    Let's plug in what we've been told in the question

    24 = (3B x B) / 2
    48 = 3B x B
    48 = 3B^2
    16 = B^2
    + or - 4 = B

    I would go with option C because if you plug in 4 in or -4 for B into the area of a triangle equation, you end up with + 24 in^2.

  6. @Lena It is B because you can't have -4 inches on a triangle.
