In a garden, there are 10 rows and 12 columns of mango trees. The distance between the two trees is 2 metres and a distance of one metre is left from all sides of the boundary of the garden. The length of the garden is
A. 20 m
B. 22 m
C. 24 m
D. 26 m
Why are you including the 1 meter given there??
The inner one is garden..
So length of garden is 11*2 = 22 only..
the one meter on the boundary are just given to confuse us..
