Question

By splitting the following figures into rectangles, find their areas (The measures are given in centimetres).

(a) (b)

Answer 1

(a) The given figure can be broken into rectangles as follows.

Area of 1^st rectangle = 4 × 2 = 8 cm²

Area of 2^nd rectangle = 6 × 1 = 6 cm²

Area of 3^rd rectangle = 3 × 2 = 6 cm²

Area of 4^th rectangle = 4 × 2 = 8 cm²

Total area of the complete figure = 8 + 6 + 6 + 8 = 28 cm²

(b) The given figure can be broken into rectangles as follows.

Area of 1^st rectangle = 3 × 1 = 3 cm²

Area of 2^nd rectangle = 3 × 1 = 3 cm²

Area of 3^rd rectangle = 3 × 1 = 3 cm²

Total area of the complete figure = 3 + 3 + 3 = 9 cm²
