Question

arianne is taking a geometry course and is working with the area of triangles. she knows the area and the height but needs to find the base. rearrange the following equation for b, where a is the area, b is the base, and h is the height of the triangle. a

Answer 1

The answer is B

Area of a triangle is given by the formula:×

                               $A=\frac{1}{2} base * height$

Now, we need to solve for b. We multiply the right side, cross multiply,  and follow rules of algebra to isolate b. Shown below:

                         $A=\frac{1}{2} base*height\\A=\frac{bh}{2} \\2A=bh\\b(base)=\frac{2A}{h}$

Thus, b is 2 times A over h, the answer choice B is right.
