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
b = 2A − h
b equals two times A over h
b = 2A + h
b = 2Ah
