2

Unit for area of a rectangle

Square units (e.g., cm², m²)

3

Length of a rectangle

The longer side of the rectangle.

4

Width of a rectangle

The shorter side of the rectangle.

5

Calculate area: length = 5 cm, width = 3 cm

Area = 5 × 3 = 15 cm²

6

Calculate area: length = 7 m, width = 2 m

Area = 7 × 2 = 14 m²

7

Find width: area = 20 cm², length = 4 cm

Width = Area ÷ Length = 20 ÷ 4 = 5 cm

8

Find length: area = 36 m², width = 6 m

Length = Area ÷ Width = 36 ÷ 6 = 6 m

9

What happens to the area if both length and width are doubled?

The area becomes 4 times larger.

10

What happens to the area if the length is halved and the width stays the same?

The area is halved.
