The perimeter of a rectangle is P = 2w + 2l where w is the width of the rectangle and l is the length of the rectangle. Rearrange this formula to find the width of the rectangular prism.

P-2L/2= w
P subtract 2L divided by 2 will give u the width

Alright, lets get started.

The perimeter of a rectangle is given by :


P = 2w + 2l

We are asked to find the width , so


P = 2w + 2l

Subtracting 2l in both sides


P - 2l = 2w + 2l - 2l


P - 2l = 2w

Divide 2 in both sides


(P-2l)/(2)=(2w)/(2)


(P-2l)/(2) = w


w =(P)/(2) - l

This is the answer.

Hope it will help :)
