A bedroom has perimeter of 46 feet. if the length of the the bedroom is 11 feet, what is the wigthof the bedroom.

Perimeter is basically the combines sum of all the bedroom's sides. It is a rectangle, therefore the formula is 2L+2W=P.

Since you are given the overall perimeter, you just plug-in the info you already have into the question. Like this: 2 (11) + 2 (W) = 46

Then solve the equation.

(2*11) + 2W=46

22+2W=46

2W = 24

W=12 Feet. The width is 12 feet.
