Answer:
1100 mm = 1.1 m, and 900 mm = 0.9 m.
So the area is 1.1 x 0.9 = 0.99 m^2

Determine the concentration at the end of 4 hours
First, calculate the amount of liquid that has been replaced at the end of the 4 hours.
This implies that, over the 4 hours; The tank has 160000 liters of liquid out of 440000 liters were replaced
Calculate the ratio of the liquid replaced.
Next, calculate the amount of solid left.
Lastly, the concentration is calculated as:
Convert L to cubic meters
You have to use pythagorean theorem which means a^2+b^2=c^2 because no angle is given
c is going to be the longest side or opp to 90 degree.
so c=13 and b=12
a^2+ (12^2)= 13^2
a^2 + 144 = 169
a^2=25
a=5
solve for a, can you do that?
a=5
hope that helps
