Q1 Find the areas of the rectangles whose sides are a 3 cm and 4 cm b 12 m and 21 m c 2 km and 3 km d 2 m and 70 cmSolution:

(a) Area of rectangle = length x breadth

= 3 cm x 4 cm = 12 cm.sq

(b) Area of rectangle = length x breadth

= 12 m x 21 m = 252 m.sq

(c) Area of rectangle = length x breadth

= 2 km x 3 km = 6 km.sq

(d) Area of rectangle = length x breadth

= 2 m x 70 cm = 2 m x 0.7 m = 1.4 m.sq
