Question

_{how much would the carpet cost to cover a 9-ft x 12-ft bedroom floor if the carpet is advertised at $35.00 per square yard ?}

Answer 1

Area = length X width

A = L(12 ft) x W(9 ft)   but since the cost of carpet is given in square yards not square feet we need to convert

A = (12 ft)(1 yd/3 ft) x (9 ft)(1 yd/3 ft)                  1 yard = 3 feet so 1 foot = 1/3 yard

A = 4 yd x 3 yd                                                  divide by 3 ft which cancels the original ft and leaves yd's

A = 12 square yards

Cost = Area x price per yard

Cost = 12 sq yd X $35.00/ sq yd                      multiply and the sq yd's cancel leaving just cost in dollars

Cost = $420.00
