You are buying fabric to make a patio umbrella in the shape of a regular hexagon, as shown. The red fabric costs $3.75 per square yard and the white fabric costs $2.50 per square yard. You can only order whole numbers of square yards of fabric. What will be the cost of the fabric for this project?

$25

Step-by-step explanation:

The area of a regular hexagon, given its side, is given by the formula:

Area = 3* side^2 * sqrt(3) / 2

As the side is 5 ft, we have that:

Area = 3 * 5^2 * sqrt(3) / 2 = 64.95 ft2

As one foot squared is equal to (1/3)^2 yard squared, we have that:

Area = 64.95/(3^2) yd = 7.22 yd2

Half of the area is red, and half of the area if white, so:

Area_white = Area_red = 7.22/2 = 3.61 yd2

We can only buy whole numbers of fabric, so we will need 4 yd2 of red fabric and 4 yd2 of white fabric. Then, the price will be:

Price = 4 * $3.75 + 4 * $2.50 = $25

the answer is c 150
