A rectangle has a perimeter of . One of its sides has a length of
.
What is the area of the rectangle?
The perimeter of a figure is the sum of the lengths of all its sides. Every rectangle has two sets of two equal-length sides. One set of sides is each, or
when added together.
We subtract from the total
perimeter to find the lengths of the remaining sides.
Since there are two remaining sides, the length of each of the remaining sides must be .
The area of a rectangle is given by multiplying the length of its longer side by the length of its shorter side.
