Question

the length,breadth and height of a rectangular swimming pool are in the ratio 4:2:3 with a total surface area of 468 m².find its dimensions​

Answer 1

Answer:

Let all ratio be 'x'

then 4x,2x and 3x

total surface area of swimming pool =468m^2 (given)

total surface area of swimming pool =2 (l+b)×h

468=2 (4x+2x)×3x

468=2×18x

36x=468

x=468/36

x=13

l=4×13=52

b=2×13=26

h=3×13=39
