If skim milk is 87% water, how much water is in 4 cups of skim milk?

Step-by-step explanation:

This problem is on the mensuration of flat shapes, this time a square shape.

we know that the area of a square is given as

area= length*length

area= l^2

from the problem   the area is given as

area= 240 units^2

substitute area for the area in the equation and then we solve for length we have

240= l^2

squareing both sides we have

√240= l

l= 15.49 units

to the nearest hundreths it is

15.5 units
