1️⃣ 8.4
2️⃣ 4.1
3️⃣ 4.4
4️⃣ 4.2​

Answer 1

answer is 4.2cm ,4 is correct

Answer 2

Given : Diagonals of a parallelogram PQRS intersect each other in point 'O'.  length of diagonal PR is 8.4 cm  

To  find : l(OP) = ?

1️⃣ 8.4

2️⃣ 4.1

3️⃣ 4.4

4️⃣ 4.2​

Solution:

Diagonals of a parallelogram PQRS intersect each other in point 'O'.  

Diagonals of a parallelogram bisect each other

length of diagonal PR  = 8.4 cm

OP = OR =  PR/2

=> OP = OR = 8.4/2

=> OP = OR = 4.2 cm

Option 4 is correct :   l(OP) = 4.2
