A 3-foot-wide wood deck will be built around a rectangular-shaped pool that measures 15 feet by 30 feet. The resulting shape is also rectangular. If the lumber costs $10 per square yard, If the lumber costs 10 dollars per square yard, what is the cost of the wood for the deck.
Area of the pool
[math]A=15(ft) * 30(ft)[/math][math]A= 450 ft^2[/math]The rectangular shape has an Area of 450 ft^2
Thanks for any hint
The area of 3-ft wide wood deck is:
[math]A= 3ft × 3 ft[/math][math]A=9 ft^2[/math].
I'm stuck here.
9 ft^2 = 1 yd^2.
What to do then?
Something is wrong because 1 yd^2 yard of lumber is 10 dollars but 10 dollars is not listed as a dollars amount on choice.
