Answer:
14km
Explanation
11km + 11km = 22km is the sum of both the width.
If you want to find the length than minus the perimeter with 22.
50km - 22km = 28km is the sum of both the length.
To know only one side of the length, divide it by 2.
28km/2 = 14km is the length

To remove √3 from denominator, we multiply both numerator as well as denominator with √3
