Question

four set of parallel lines intersected by another set of four parallel lines.how many parallelograms formed?

Answer 1

Answer:

Step-by-step explanation:

Individual parallelogram=9

parallelogram formed with 2 parallelograms = 12

parallelogram formed with set of 3 parallelogram=6

Parallelogram formed with the set of 4 =4

Parallelogram formed with set of 6 parallelograms =4

And at last the biggest parallelogram with 9 total parallelograms =1

When we add all the number of parallelograms =9+12+6+4+4+1

=36

Therefore,total 36 parallelograms are formed.
