Moving to the edges it travels 2*3 + 2*2 = 10 units.
Then it moves in a circular path when it turns the 4 corners.
It goes through 90 degrees in each case - or pi/2 units
so 4 turns = 4 * pi/2 = 2 pi units
Answer is 10 + 2 pi.
Option D
Answer:
3/8 of the total floor is covered by red carpeting
Step-by-step explanation:
15
13.70
a^2+b^2=c^2
a = side 1
b = side 2
c = hypotenuse
9.2^2 + b^2 = 16.5^2
272.25 - 84.64 = 187.61 =b^2
√187.61 = b = 13.697 = 13.70
