Answer: [tex]\dfrac{p}{2}-w[/tex]
Step-by-step explanation:
Given : A formula for finding the perimeter of a rectangle is [tex]p=2l+2w[/tex].
To derive the formula for length (l), we first need to subtract 2w on both sides, we get
[tex]p-2w=2l[/tex]
Divide both sides by 2 , we get
[tex]l=\dfrac{p-2w}{2}=\dfrac{p}{2}-w[/tex]
Hence, the formula can you use to find the length (l) =[tex]\dfrac{p}{2}-w[/tex]
