Maria has decided to plant grapes in the garden behind her house.
His neighbor Ben has grown grapes successfully for a long time and has given Maria advice
on how to plant vines. Ben told her to plant them three meters apart in rows
that are also three meters apart. Maria has measured the size of her garden and learned
that it's a rectangle with sides of 25 meters and 35 meters. How many vines should Maria buy?
~~~~~~~~~~~~~~~~~~~~~
A reasonable interpretation is that with each bush, a square of 3 x 3 meters is associated
and the bush is in the center of this square.
If so, the number of bushes along the dimension of 25 m is the integer part
of the ratio 25/3, which is 8.
The number of bushes along the dimension of 35 m is the integer part
of the ratio 35/3, which is 11.
Thus, the number of bushes to buy is 8*11 = 88. ANSWER
Solved.
