Question

 

 

A swimming 20 m wide by 70 m long, 1 m deep at the shallow end and 3 m deep at the other end.  Find the total surface area of the pool.

Answer 1

yer draw is 2 big...hard tu get idea wot yu sho

me thank yu hav rektangel 25 bi 60

area=25*60=1500 squares

****

mi ges is deep=1 at 1 end & 3 at other end with strate line tween em

so averaej deep=2

volume=2*1500=3000

Answer 2

length=70m

width=20m

depth (or height)=(1+3)/2=2m

surface area of pool=2{(length*width)+(width*height)+(height*length)}

2{(70*20)+(20*2)+(70*2)}

2(1400+40+140) = 2(1580)

ANS=3160 cubic metre
