Perimeter of a Rectangle
The formula to find the perimeter of a rectangle is as follows:
[tex]P=2l+2w[/tex]
- [tex]l[/tex] = length
- [tex]w[/tex] = width
Solving the Question
We're given:
- [tex]w[/tex] = 7 inches
- [tex]P[/tex] = 63 inches
- We are solving for [tex]l[/tex]
⇒ Plug the given information into the perimeter formula and solve for l:
[tex]P=2l+2w\\63=2l+2(7)\\63=2l+14\\49=2l\\l=24.5[/tex]
Answer
Therefore, the length of the desk is 24.5 inches.
