Question

PLEASE HELP

If Janice is building a garden and the perimeter is 20 (P = 20) and the length is 4 (L = 4), find w (the width)

Answer 1

w = 6 units

Explanation:

The perimeter is found by adding all the sides of a rectangle. The perimeter can be found using this equation:

`P=2w+2l`

Where w represents width and l represents length.

To find the width, rearrange the equation so it is in terms of w:

`P=2w+2l\\2w=P-2l\\w=(P-2l)/(2)`

Now, plug in the known values!

`w=(20-2(4))/(2)`

Simplify!

`w=(12)/(2) \\w=6`
