carpet is usually priced by the square yard.
8 yd by 7 yd =
24 ft by 21 ft =
504 ft²
504 ft² • $8.5 / ft² = $4284

the answer is that the carpet will cost 47.53 (actually like 47.529... i rounded to the nearest hundredth) remember, 3 feet in one yard 8= 24ft.. 7=21ft. multiply 21 and 24 to get 404 and divide by 8.50

so you need to know how many foot are in a yard
1 yard = 3 feet
8x3=24 feet
7x3=21 feet
so room is 24 by 21 feet
area is 24x21=504
504X8.5=4284 dollers

8 times 7 = 56. $8.50 times 56 = $476.00.

8*7=area=24ft*21ft=504
504*8.5=$4284
3 feet in a yard.
1 yard = 3 feet

basic formula:
1 yd = 3ft
1 sq yd = (1yd ) * (1 yd)
= (3 ft) * (3 ft)
= 9 ft * ft
1 sq yd = 9 sq ft
area of room = 8 yd * 7 yd = 56 sq yd
= 56 sq yd
= 56 * (1 sq yd)
= 56 * ( 9 sq ft)
= 504 sq ft
cost = 8.5 * 504 = $4,284.00
