4*2.5 = a perimeter of 10 inches
A pentagon is a 5-sided figure, and the perimeter is the sum of the lengths of all the sides. A pentagon with 15-inch sides, will have 5 x 15 inches = 75 inches as its perimeter.
Add all the sides up
Perimeter is the measurement of all sides of a figure. For example, if you have a rectangle that has 2 sides of 4 inches long and 2 sides of 8 inches long, the perimeter is the total of all sides, which in this case is 24 inches.
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.
A pentagon is a 5-sided figure, and the perimeter is the sum of all the sides. If a pentagon has sides of 6 inches, it has 5 x 6 inches = 30 inches for a perimeter.
