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.
