Question

A formula for finding the area of a rectangle is A=l⋅w. If you know the area (A) and length (l) of a rectangle, which formula can you use to find the width (w)?

Answer 1

w=A/l, easy.

Answer 2

Mind showing me how to do it so in the future I got it?

Answer 3

divide both sides by W

Answer 4

Or better do this....

Answer 5

Thanks, but also I got another one I need help on, A formula for finding the perimeter of a rectangle is P=2L+2W. If you know the perimeter (P) and width (W) of a rectangle, which formula can you use to find the length (L)?

Answer 6

It's a simple algebraic work, which doesn't have any step.

Answer 7

2w=p-2l => w=p/2 - l

Answer 8

Alright, thanks,

Answer 9

Aight, if you find it helpful, give me a medal and close this question! ;)

Answer 10

Got it.
