<u>Answer:</u>
The length of VI = 4 cm
<u>Solution: </u>
The plot is like a quadrilateral and the fences are built on the diagonal
We know that for quadrilateral both the diagonals are in same height,
So as per the picture, GH = FI
Now we know that GV = 6.55, FV = 5.84, VH = 3.27
Hence,
GH = FI
<u><em>Rounding off: </em></u>
- If the number that we are rounding is<em> followed by 5 to 9</em>, then the number has to be <em>increased to the next successive number</em>.
- If the number that we are rounding is <em>followed by 1 to 4</em>, then the number has to <em>remain the same</em>.
Here the number to be round off is 3.98, 9 belongs to the first category stated above. So, 3 is increased to 4.
Hence, the length of VI = 4 cm.
