Answer:
see explanation
Step-by-step explanation:
The perimeters of the similar figures have the same ratio as the sides.
ratio of perimeters = 
ratio of areas = 11² : 6² , that is 121 : 36
ratio of areas = 
sides of right angle triangle follows Pythagoras theorem
a^2 + b^2 = c^2
where a, b and c are sides of triangle
if you check, option 3 follow this. so answer is option 3
Answer:
6.5e^(i·(-157.38°)) ≈ 6.5e^(-2.7468i)
Step-by-step explanation:
A suitable calculator can find the value of this ratio for you.
((2+3i)/(1-i))² = -6 -2.5i ≈ 6.5∠-157.38° ≈ 6.5e^(-2.7468i)

The second attachments shows the calculator set to radian mode for the angle measure.
40+60=100. So one person equals 1%, meaning 40% are boys and 60% are girls. By simplifying, we will find that possible ratios below the value of 100 are 40:60, 4:6, 2:3, and 20:30.
