This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th is 9 (although i doubt saying 1th is right, but just because).
Percentage of down payment that ABC bank requires to be paid = 20% Price of the house = $10500 Then Amount of down payment that needs to be made = (20/100) * 105000 = 21000 dollars From the above deduction, it can be deduced that the correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has actually come to your desired help.
