Question: what is the maximum area of a rectangle with a perimeter of 100?
Answer: By assuming, If length & width equals, it becomes square and area is the biggest i.e. 25 * 25 = 625 sq cm. But, length will be bigger. Hence greatest possible area of this rectangle will be if length is 26 cm and width is 24 cm. So area will be 26*24 = 624 sq cm.
