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".

An artist is hired to create an art display for the interior of a city building. The display is to span a total width of 10 yd .
lesya692 [45]

Answer:

8 portraits are going to be used in the display.

Step-by-step explanation:

This problem can be solved as a rule of three problem.

Each yd has 36 inches.

The display is to span a total width of 10 yd. So it is a total width of 360 inches.

Each portrait has a width of 45 in. How many portraits can there be?

1 portrait - 45 in

x portraits - 360 in

45x = 360

x = 8

8 portraits are going to be used in the display.
