Question

The formula for the area of a triangle is A=12bh. Solve this equation for b.

Answer 1

`(2a)/(h) = b`

Explanation:

The formula for the area of a triangle is:

`a = (1)/(2) (bh)`

to solve for b, multiply both sides by 2...

`2a = bh`

then divide both sides by h...

`(2a)/(h) = b`

Answer 2

Explanation:

Hey there!

Given;

[A = 1/2b*h]

Divide both sides by 'h'.

A/h = 1/2(b*h/h) [ on right side'h' gets cancelled].

Multiply '2' and 'A'.

A*2/h = b

b = 2A/h.

Hope it helps...
