What will it cost to carpet a rectangular floor measuring 9 feet by 21 feet if the carpet costs $26.50 per square yard? A plastering contractor charges $18 per square yard. What is the cost of plastering 60 feet of wall in a house with a 9-foot ceiling?

Solution

37 ) Area of rectangle = length x breadth

Given that

length = 9 feet

breadth = 21 feet

Area of rectangular floor = 9 feet x 21 feet = 189 square feet

1 square feet = 0.111 square yard

Hence,

Area of rectangular floor = 189 square feet = 189 x 0.111 square yard = 21 square yard

Given that

Cost of carpet = $ 26.50 per square yard

Therefore,

cost of carpeting given rectangular floor = 21 square yard x $ 26.50 / square yard

=  $ 556.50
