An artist decides to frame a photo that is 9 inches
wide and 12 inches in height. To calculate how
much material she'll need, she uses the formula
for the perimeter of a rectangle: P = 2h + 2w.
what is the perimeter of the 9 inch by 12 inch photo

Sagot :

The perimeter of the rectangle is 42 inches.

Description of a rectangle

A rectangle is a four-sided object. The sum of angles in a rectangle is 360 degrees.

The formula that can be used to determine the perimeter of a rectangle is: 2h + 2w

Where:

  • h = height
  • w = width

Perimeter of the photo

2h + 2w = (2 x 9) + (2 x 12)

= 18 + 24

= 42 inches
