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) 2m and 70cm. |
|
Answer» It is known that Area of rectangle = length × Breadth (a) 1 = 3 cm, b = 4 cm Area = l × b = 3 × 4 = 12 cm2 (b) 1 = 12 m, b = 21 m Area = l × b = 12 × 21 = 252 m2 (c) l = 2 km, b = 3 km Area = l × b = 2 × 3 = 6km2 (d) l = 2 m , b = 70 cm = 0.70 m Area = l × b = 2 × 0.70 = 1.40 m2 |
