You can put this solution on YOUR website! As a rectangle is bounded by two pairs of equal sides a and b, the formula for its perimeter is: .
Or
If we are talking about length and width.
The length of a rectangle is 7 feet longer then twice the width.
Now we can plug in the place of L in the formula for perimeter and 86 for in the place of P.
Expand the bracket and collect like terms:
The width of the rectangle is 12 feet.
Finding length:
Its length is 31 feet.
Now you want to check.
All good.
