A 125%
B 150%
C 200%
D 375%

Correct Answer: 375%

Let, the length of each side of the garden = 100 Area = 1002 = 10000 Area of 3 square = 3×10000 = 30000 50% increase of length = 100 + 100×50/100 = 150 Area = 1502 = 22500 Area of 3 square = 3×22500 = 67500 Increasing area = 67500 - 30000 = 37500 Percentage = (37500×100)/30000 = 125%
