Area and Perimeter 4.5 D

Area is the amount of space inside a two-dimensional shape, measured in square units.

Perimeter is the total distance around the outside of a two-dimensional shape.

Area = length × width.

Perimeter = 2 × (length + width).

Area = 4 m × 3 m = 12 square meters.

Perimeter = 2 × (4 m + 3 m) = 14 meters.

You need to find the area to know how much material is needed to cover the entire surface.

You need to find the perimeter to know the total length of the border.

Area is measured in square units, such as square meters (m²) or square feet (ft²).

Perimeter is measured in linear units, such as meters (m) or feet (ft).
