Question 1068196
Before even starting to solve this problem, remember that the dimensions that are given to us are in units of feet (23 ft by 15 ft). So we can solve for the area with square feet and then convert to yards. 
(1 YARD = 3 FEET)

Area = length x width 
Area = 23ft x 15ft 
Area = 345 square feet

Divide 345 by 3 and the quotient should be 115 square yards.

Now it costs $49.50 PER square yards, so $49.50 x 115 = $5692.50.
