Answer:
The length of OR = 3.12
Explanation:
In a parallelogram:
LM = 4.12
MN = 4
LN = 5 = 2.5 (divided by 2)
OM = 6.4
where LN and OM are diagonals. We will find the length of OR.
Now by applying the Pythagorean theorem:
b = √c²-a²
OR= √(4)²-(2.5)²
OR = √16-6.25
OR = √9.75
OR = 3.12
Thus the length of OR = 3.12 ...
