C. Now look at the shapes below and find the area and perimeter of each one. Use the graph paper below each shape to show your maths.

1. Length = 11 cm, Height = 3 cm. Perimeter = 2 × (11 + 3) = 2 × 14 = 28 cm. Area = 11 × 3 = 33 cm². 2. Base = 12 cm, Height = 5 cm, Side = 13 cm. Perimeter = 12 + 13 + 5 = 30 cm. Area = (12 × 5) ÷ 2 = 60 ÷ 2 = 30 cm². 3. Width = 8 cm, Height = 8 cm. Perimeter = 2 × (8 + 8) = 2 × 16 = 32 cm. Area = 8 × 8 = 64 cm².
