Question

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.

Answer 1

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

Answer 2

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 :)
