**Measure and calculate perimeter of composite 2-D shapes.**

Afiqah make a few
composite 2-D shapes from some cards.
Measure and calculate the
perimeter of the shapes.

(d)

(e).Measure the perimeter of the
following composite 2-D shapes using a ruler.

(f). Calculate the perimeter of the
following composite 2-D shapes.

**Measure the area of composite 2-D shapes.**

The area of each small square is 1 cm². Find the area of the
composite shapes.

(a)

Area A = 9 x 1 cm²
= 9 cm²

Area B = 4 x 1 cm²
= 4 cm²

Total area = 9 cm²
+ 4 cm²

= 13 cm²

Area A = 4 x 1 cm²
= 4 cm²

Area B = 12 x 1 cm²
= 12 cm²

Total area = 4 cm²
+ 12 cm²

= 16 cm²

(c).

Area A = 3 x 1 cm²
= 3 cm²

Area B = 7 x 1 cm²
= 7 cm²

Total area = 3 cm²
+ 7 cm²

= 10 cm²

**Find area of the composite 2-D shapes below.**
