The Muslim mathematicians adopted a numerical system from India. The correct answer is B.
Answer:
P = 46.6 feet
Step-by-step explanation:
P = 2L + 2W, where P is perimeter, L is length, and W is width.
2 x Length (L) = 2 x 15.5 feet = 31 feet;
2 x Width (W) = 2 x 7.8 feet = 15.6 feet.
Add both length and width together:
2L + 2W = 30.1 + 15.6 = 46.6 feet.
The perimeter (P) = 46.6 feet.
