Answer:

Part A) The perimeter of the court is
P=139.25\ ft

Part B)
5\ cans

Explanation:

Part A) we know that

The perimeter of the court is equal to the perimeter of the square plus the perimeter of semicircle


P=4D+(\pi D )/(2)

we have that


D=25\ ft

substitute


P=4(25)+((3.14*25))/(2)


P=139.25\ ft

Part B)

Find the area above the foul line (labelled II)

The area of a semicircle is equal to


A=(\pi r^(2))/(2)

we have


r=25/2=12.5\ ft

substitute


A=((3.14)(12.5)^(2))/(2)


A=245.31\ ft^(2)

Round to the nearest whole number


A=245\ ft^(2)

One can of paint covers 50 square feet of floor

so

Calculate how many cans of blue paint does the school need to purchase


245/50=4.9\ cans

Round up


5\ cans
