Question

A banner is in the shape of a rectangle.It is 18 feet long and 9 feet wide.What is its perimeter?

Answer 1

The given problem can be exemplified in the following diagram:

The perimeter of a figure is the sum of all of its sides, therefore, the perimeter of the figure is:

`P=18ft+18ft+9ft+9ft`

Adding the terms:

`P=54ft`

therefore, the perimeter is 54 feet.
