You can put this solution on YOUR website! This problem is missing the price for a block of stone.
Just for example, block of stone price is some x dollars per square yard.
Offer is some y total payment.

The corner lot is square, and 61 blocks each a yard square were used to lay a sidewalk facing both streets. That means 30 of those blocks were facing each street, with the 61st block on the corner.
So, assuming the sidewalk was not part of the lot, the lot was 30 yards square, or 90 feet square, making the area of the lot 90*90 = 8100 square feet.
His profit on selling the lot was $100 per square foot, which is 8100*$100 = $810000.
ANSWER: $810,000
Note if the lot included the area of the sidewalk, simply do the same calculations using 31 yards = 93 feet instead of 90 feet for the side length of the lot....
