Ex 10.3, 10 (b) By splitting the following figures into rectangles, find their areas (The measures are given in centimeters). Our rectangles are ABCQ, QDEP, PFGH QD Finding sides, GH = QD + CD 3 = QD + 2 3 − 2 = QD 1 = QD QD = 1 AB By symmetry GH = AB 3 = AB AB = 3 Rectangle ABCQ Length = l = 1 Breadth = b = 3 Area = l × b = 1 × 3 = 3 cm2 Rectangle QDEP Length = l = 3 Breadth = b = 1 Area = l × b = 3 × 1 = 3 cm2 Rectangle PFGH Length = l = 1 Breadth = b = 3 Area = l × b = 1 × 3 = 3 cm2 Area of figure = 3 + 3 + 3 = 9 cm2
