Ming must add 0.375 L of a 10% sugar solution
Step-by-step explanation:
if 3 L = 80%
1.5 L should = 40% (since it is half of 80%)
and if 40 divided by 4 = 10%
1.5 also needs to be divided by 4
so 1.5 divided by 4 = 0.375
that means Ming must add 0.375 L of a 10% sugar solution

Explanation:
So you want to start by finding the area of the big square.
We know the width to the big square is 60cm. The length to the big square is

Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.
Little square

The area enclosed is the area of the big square minus the area of the little square.
