# Real Estate Math Class : Lesson 159

A piece of land 500 feet by 350 feet had a sidewalk laid around it by the owner.

The sidewalk encompassed the entire lot and a curb was placed along the lot lines.

The sidewalk cost \$32,000 and the curb was \$20 per lineal yard.

What was the total cost of the sidewalk including the curb ?

A. \$43,333.33

Remember that we're looking for a linear yard (3 feet) and not a cubic yard.

First, find out what the total perimeter of the curb is by adding 500 plus 500 plus 350 plus 350 and we get the total perimeter of the curb is 1700 feet.

Now, remember we want linear yards and not cubic so divide 3 (feet) into 1700 for a total of 566.666667 yards.

Multiply 566.666667 yards times \$20 per linear yard aqnd we find that we have a cost of \$11,333.33334 dollars.

Add \$11,333.33334 dollars to our sidewalk cost of \$32,000 and we have a total cost of \$43,333.33334 or rounded \$43,333.33.
