A man divided his circular piece of land, measuring 1100 sq. m, between his two sons. He gave his elder son a square piece of land within the circular piece. He gave his younger son the remaining part around the square. However, he compensated his younger for this awkward shaped land by giving him 20% more than what he gave to his elder son. What is the length of the side of the square-piece land?
Let the length of the side of the square-piece land be x.
Area of the square piece land = x2
As per the question,
x2 + (x2 + 20% of x2) = 1100
