Q.11 Split the following shapes into rectangles and find their areas. (The measures are given in centimetres)

(a) Area of rectangle ABCD = 2 x 10 = 20 \(cm^2 \)
Area of rectangle DEFG = 10 x 2 = 20 \(cm^2 \)
Total area of the figure = 20 + 20 = 40 \(cm^2 \)

(b) There are 5 squares each of side 7 cm.
Area of one square = 7 x 7 = 49\(cm^2 \)
Area of 5 squares = 49 x 5 = 245 \(cm^2 \)
(c) Area of rectangle ABCD = 5 x 1 = 5 \(cm^2 \)
Area of rectangle EFGH = 4 x 1 = 4 \(cm^2 \)
Total area of the figure = 5 + 4 \(cm^2 \)
