richie has a rug in his bedroom with a perimeter of 42 feet. the length of the rug is 12 feet what is the width of the rug

Usimov [2.4K]

The width of the rug is 9 feet.

Step-by-step explanation:

Perimeter of rug = 42 feet

Lengths are same in square and rectangle shapes; therefore;

Length of rug = 12 feet

Width of rug = w

Perimeter = Length + Length + Width + Width

Perimeter = $12+12+w+w$

$42=24+2w\\42-24=2w\\18=2w\\2w=18$

Dividing both sides by 2

$\frac{2w}{2}=\frac{18}{2}\\w=9$

The width of the rug is 9 feet.
