Question

a rectangular brass sheet of length 1.5 m and breadth 75 cm weigh 7.2 kg find the area in m2 of another similar sheet of brass weighing 12.8kg ​

Answer 1

Answer:

length of rect. sheet = 1.5m

breadth of rect. sheet = 0.75m

Area of rect sheet = l*b

= 1.5*0.75

= 1.125m²

Area of 7.2kg of sheet = 1.125m²

Area of 1 kg of sheet = 1.125m²/7.2

Area of 12.8kg of sheet = 1.125/7.2*12.8

= 2m²
