As shown in Figure 107.13103, you must install lights in a new triangle-shaped sidewalk on the job site. Your concrete requires that this area be poured with concrete around your lights, and you will have a concrete contractor finish it.
The concrete contractor charges you by the number of square yards. If you’re able to finish his invoice, it should be for:
a. 49.73
b. 22.31
c. 36.88
d. 18.44
e. 55.31 square yards
The area of the triangle-shaped sidewalk is approximately 18.44 square yards, which matches option d. 18.44.
