## A certain type of siding for a house costs $10.50... A certain type of siding for a house costs$10.50 per square yard. What does it cost for the siding for a wall 4 yards wide and 60 feet long?

A. $800 B.$840
C. $2520 D.$3240
E. $5040 The OA is B. To solve this PS question, I just need to find the total area in yards of the siding that has 4 yards wide and 60 feet long, right? I need to convert the 60 feet to yards and then determine the area and get the total cost multiplying the total square yards by$10.50.

I appreciate if any expert explains it to me. Thank you so much.

Thank you so much. Hi AAPL, Let's take a look at your question. Since the cost is given according to per square yard, therefore we will convert the length in yards as well. We know that: $$1\ ft=\frac{1}{3}yards$$ $$60\ ft=60\times\frac{1}{3}yards=20\ yards$$ $$Length=20\ yards$$ $$Width=4\ yards$$ $$Area\ of\ wall=Length\times Width$$ $$Area\ of\ wall=20\times4=80\ square\ yards$$ Now, we can find the cost of siding on the wall. $$Cost\ of\ siding\ per\ square\ yard=10.50$$ $$Cost\ of\ siding\ on\ 80\ square\ yards=80\times10.50=840$$ Therefore, Option B is correct. Hope it helps. I am available if you'd like any follow up. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.

A. $800 B.$840
C. $2520 D.$3240
E. $5040 Since 60 feet is 60/3 = 20 yards, the area of the wall is 4 x 20 = 80 yards^2. Thus, it will cost 80 x 10.5 = 840 dollars.
