The number of islands and peninsulas visited by Ni Hua are = 191919.
<h3>Multiplication of whole numbers:</h3>
The number of times he skydived in island is = 191919 ×2
= 383838
The number of times he skydived in peninsulas= 191919×3
= 575757

The set of parallel lines in a quadrilateral leads to the parallelogram.
<h3>What is a quadrilateral?</h3>
Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral.
Line M
x - y + 3 = 0,
y = x + 3
m = 1
Line L
y = x - 2,
m = 1
Line N
y = -1/2x + 5,
m = -0.5
Line P
x+2y+12=0
y = -x/2 - 6
m = -0.5
Here we can see that the slope of line M and L are equal and slope of line N and P are equal.
That quadrilateral in which opposite sides are parallel is called a parallelogram.
Hence, the set of parallel lines in a quadrilateral leads to the parallelogram.
