Step-by-step 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...
Answer:
[tex] \frac{2a}{h} = b[/tex]
Step-by-step explanation:
The formula for the area of a triangle is:
[tex]a = \frac{1}{2} (bh)[/tex]
to solve for b, multiply both sides by 2...
[tex]2a = bh[/tex]
then divide both sides by h...
[tex] \frac{2a}{h} = b[/tex]
