The answer is below
Step-by-step explanation:
The sprinklers have a radius of 5 ft each. Since the larger semicircle (entire lawn) has a diameter that is formed from the 2 semicircles, therefore the radius of the larger semicircle is 10 ft.
Area that wont be watered can be gotten by subtracting the area of the two smaller circles from the area of larger semicircle.
Area that wont be watered = 1/2(π * 10²) - 2[1/2(π * 5²)] = 50π - 25π = 25π ft²
