Rhombus 48

A rhombus consists of four identical rhombuses with an area of ​​42 m2. The angle alpha of each rhombus is 60°. What is its perimeter?

Correct answer:

o =  55.7121 m

Step-by-step explanation:

S1=42 m2 α=60   S1 = a2   sin α a=S1/sinα=S1/sin60° =42/sin60° =42/0.866025=6.96401 m  b=2 a=2 6.96413.928 m  o=4 b=4 13.928=55.7121 m
