Question

Fred wants to put a carpet in this room. The carpet costs $15.00 a square yard, how much would it cost for a 3 ft by 6 feet by 9ft by 12 ft

Answer 1

Solution :

Cost of carpeting per square yard = $ 15.00

For 3 ft by 6 ft

1 yard = 3 feet

∴ 1 feet =  $\frac{1}{3}$ yard

So,

Therefore, area of 3 ft by 6 ft is = $3 \times \frac{1}{3} \times 6 \times \frac{1}{3}$

                                                    = 1 x 2

                                                    = 2 square yard

Therefore, cost of carpeting 2 square yard = 2 x 15

                                                                       = $ 30

For 9 ft by 12 ft

1 yard = 3 feet

∴ 1 feet =  $\frac{1}{3}$ yard

So,

Therefore, area of 9 ft by 12 ft is = $9 \times \frac{1}{3} \times 12 \times \frac{1}{3}$

                                                    = 3 x 4

                                                    = 12 square yard

Therefore, cost of carpeting 2 square yard = 12 x 15

                                                                       = $ 180
