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

B

Step-by-step explanation:

Area of a triangle is given by the formula:

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

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

step-by-step explanation:

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
