Question

The Romubus diagonal are 60m 30m find its perimeter

Answer 1

Using the formulas the answer is 134.16m

Answer 2

Answer:

60√5 m

Step-by-step explanation:

since diagonals of a rhombus bisect each other at 90°, we can use Pythagoras Theorem to find the length of one side.

Let d₁=60 and d₂=30

since they bisect each other, it becomes d₁= 30 m and d₂=15 m respectively.

now we use Pythagoras Theorem,

Let a be side of the rhombus. now:-

⇒30²+15²=a²

⇒a²=1125

⇒a=√1125

⇒a=15√5 m

Now perimeter is 4a

thus 4×15√5=60√5.

∴Perimeter is 60√5 m
