Question

1. 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 Find the areas of the soun (d) 2 m and 70 cm​

Answer 1

The area of rectangle = l × b

(3 × 4) = 12cm

(12 × 21) = 252m

(2 × 3) = 6km

If 1m = 100cm

then 70cm = 0.7 m

so area = (2 × 0.7) = 1.4m

HOPE THIS IS HELPFUL TO YOU
