Perimeter is the distance around the outside of a shape. It is the total length of all the sides of a shape. To find the perimeter of a shape, you simply add up the lengths of all its sides.
Here are the formulas for finding the perimeter of some common shapes:
Let's work through a couple of example problems to practice finding the perimeter of different shapes:
Perimeter = 2 * (5 + 3) = 2 * 8 = 16 cm
Perimeter = 4 * 6 = 24 cm
Perimeter = 4 + 7 + 9 = 20 cm
Perimeter = 2 * π * 5 = 10π cm (or approximately 31.42 cm if using 3.14 for π)
Here are some tips for studying and mastering the concept of perimeter:
With regular practice and understanding of the formulas, you'll become a pro at finding the perimeter of any shape!
