Question

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

Answer 1

The formula to find the area is
A = l • w
To find the formula that can be use d to find the length I, you just divide both sides by W to get
I=A/w which is the formula that can be used to find the length

Hope it helps!

Answer 2

Take the area and divide out what you know, so if you know (w) then divide (w) out from the area
