Q.10 By splitting the following figures into rectangles, find their areas (The measures are given in centimetres).

(a) Area of HKLM = 3 x 3 =\( 9 cm^2\)
Area of IJGH = 1 x 2 = 2 \(cm^2\)
Area of FEDG = 3 x 3 = 9 \(cm^2\)
Area of ABCD = 2 x 4 = 8 \(cm^2\)
Total area of the figure = 9 + 2 + 9 + 8 = 28 \(cm^2\)
(b) Area of ABCD = 3 x 1 = 3 \(cm^2\)
Area of BDEF = 3 x 1 = 3 \(cm^2\)
Area of FGHI = 3 x 1 = 3 \(cm^2\)
Total area of the figure = 3 + 3 + 3 = 9 \(cm^2\)
