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 = one half b times h

A.b = 2A − h
B.b equals two times A over h
C.b = 2A + h
D.b = 2Ah

Answer:

B

Step-by-step explanation:

Area of a triangle is given by the formula:

[tex]A=\frac{1}{2}bh[/tex]

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

[tex]A=\frac{1}{2}bh\\A=\frac{bh}{2}\\2A=bh\\b=\frac{2A}{h}[/tex]

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