Question

plz solve both of them...

Answer 1

Hey...



Rainfall = 5cm = 5/100 m

2 hectares = 10,000x2 =20,000m2

So, Volume = (l x b)xh

= (20,000 x 5)/100

= 1000m3







Given that: Rate of water flow = 3km/h= (3000/60) m/min =50 m/min

Depth (h) of river = 2 m

Width (b) of river = 45 m

Volume of water flowed in 1 min = Rate of water flow * depth of river * width of river = 50*2*45 = 4500 m3

Hence, in 1 minute, 4500 m3 water will fall in the sea





Hope this helps u and please mark the brainliest.........



Thanks......
