We can see from the diagram that the length of the rectangle is 2 lots of the radius of one quarter circle. The width is made up of one radius, therefore the width is half of the length.
This means that the width of the rectangle is 9cm, and the radius of each quarter circle is 9cm.
To find the shaded area, we find the area of the rectangle and subtract from the areas of each circle, which are equal:
A = lw - 1/2(pi x r^2)
A = 9 x 18 - 1/2(81pi)
A = 162 - 81/2 pi
A = 34.8cm (3sf)
Half of 57 is 28.5. Hoped I helped. :)

Answer:
I have gotten 216/61, but I am not sure if this is right.
Step-by-step explanation:
By using the "Keep It, Change It, Flip It" tactic, I was able to come up with an answer and simplify it.
1. Keep the original divisor.
162/3
2. Change the sign.
Division becomes multiplication.
3. The last fraction is reciprocated.
61/4 becomes 4/61.
