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 = 1/2bh

b = 2A − h
b = 2A/h
b = 2A + h
b = 2Ah

Answer:

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

Step-by-step explanation:

∵ Area of a triangle,

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

Where,

b = base of the triangle,

h = height of the triangle,

For finding the formula for b we need to isolate b in equation (1),

For this divide both sides by [tex]\frac{1}{2}h[/tex]

We get,

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

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

Hence, SECOND option is correct.

Answer:

B

Step-by-step explanation:

B
