# A rectangle has a width of 7cm and a length of 9cm. What is its perimeter?

32cm

Explanation

The perimeter of a figure is the sum of all of its sides. Since a rectangle's width and length will be the same on opposite sides, the perimeter of a rectangle can be calculated by using the following formula: perimeter = 2(width) + 2(length) Using the numbers given in the question:
perimeter = 2(7cm) + 2(9cm)
perimeter = 14cm + 18cm perimeter = 32cm
