The answer is 133 dollars cuz 5580-3186 is 2394 and 2394 divided by 18 is 133
Area=length*width
(32+48)=(16)*(width)
80=(16)(width)
width=(80/16)
5=width
divide 50 by 6.2, because 6.2 and x are entangled by multiplication. once you do that, you will have your answer. it should be 8.06
Let us assume the length of a side of the square floor = x feet
Area of the square floor as given in the question = 320 square feet
Then
x^2 = 320
x^2 = (17.89)^2
Then
x = 17.89
= 18 feet approx
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the second option or option "B".
