A pentagon is a 5-sided figure. The perimeter is the sum of all the sides of a figure, and if a pentagon has 16-foot sides, it will have 5 x 16 feet = 80 feet as its perimeter.
5x2 + 3x2 = 16
1 as squares have to have equal sides
When the linear dimensions of a plane figure are quadrupled, its perimeter is quadrupled, and its area is multiplied by 42 = 16 .
The perimeter is the sum of the lengths of all the sides of a figure. If there are only two sides, it is their sum. In this case it would be 16 inches.
