Perimeter of shapes
4th Grade Math practice: A rectangular garden is 9 meters long and 4 meters wide. What is its perimeter. Part of area and geometry (Area and Geometry).
~8 min
Perimeter is found by adding the side lengths around the outside of a figure.
Perimeter is Distance Around
8 (length)5 (width)
Perimeter = 2 × (8 + 5) = 26
Area = 8 × 5 = 40
Perimeter is the total distance around the outside edge of a shape. It measures the length of the boundary, like a fence around a yard.
💡 Imagine an ant walking all the way around the outer edge of the shape!
