Question 796773: Far-west construction has just built a new auto parts store. They plan to add a concrete sidewalk that would wrap around the perimeter of the store and would be 4ft wide at all points. The store is rectangular shaped and had a measurement of 75ft by 32ft. what will the area of the sidewalk be

i've actually worked concrete for the last 14 years :)
find out the entire length of sidewalk you will create first, it will be 4' wide all around, so we will just add 4' to the length of the building on both sides, and this would be the formula...
75+75+4+4+32+32 = 222' long
now we know the length, area is simply length times width
222 x 32 = 7104 square feet
hope this helps :)
p.s. if you were to figure out how much concrete you actually needed for this, it would be ((l x w x d)/27)1.05 length times width times depth divided by 27 (number of cubic feet in a cubic yard) then add 5 percent to the whole thing to account for low spots. sidewalks are usually 4 inches deep, so this pour would end up being.... 91.168 cubic yards, we would round it up to 92 yards of concrete total since you order it by the whole yard. that would be a BIG job
