# Q.1 Find the area 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 cm

Answer :

Area of rectangle = Length × Breadth
(a) l = 3 cm and b = 4 cm
Area = l × b = 3 × 4 = 12 $$cm^2$$
(b) l = 12 m and b = 21 m
Area = l × b = 12 × 21
= 252 $$m^2$$
(c) l = 2 km and b = 3 km
Area = l × b = 2 × 3
= 6 $$km^2$$
(d) l = 2 m and b = 70 cm = 0.70 m
Area = l × b = 2 × 0.70
= 1.40 $$m^2$$
