<u>Answer:</u>
The length of VI to the nearest tenth is 4 cm
Solution:
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, 
Now we know that 
Hence,
<u>Rounding off:</u>
- If the number that we are rounding is followed by 5 to 9, then the number has to be increased to the next successive number.
- If the number that we are rounding is followed by 1 to 4, then the number has to remain the same.
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.
If you have to estimate I will put $85 and then to find 20 % you just have to kniw that 10% is equal to 8.5 you just move a decimal then you just add 8.5 plus 8.5 = 17 so 20% of 85 is equal to $17 and to find 15% you already know how much is 10%=8.5 so you just need to find 5% that is equal to 4.25 and then you just add 4.25 to 8.5 and that's equal to 12.75
20%= 17
15%=12.5
40min*1.05=42min they spent 42 min together
ps: check the multiplication it's 01:30 and I did that in head
Step-by-step explanation:
☄ 
- Length of a park ( l ) = 55 m
- Breadth of a park ( b ) = 35 m
- Width running outside the park ( d ) = 2.5 m
- Rate of paving the path with stones = Rs 120 per sq.metre
☄ 
- Area of the park
- Cosy of paving the path with stones at Rs 130 per sq.metre
☄
