During the next Tree Plantation Week, DBBL is considering planting trees in one of its rectangular piece of land which is 90 feet long and 66 feet wide. The land is surrounded by boundary wall of 5 feet height. It has been decided that trees will be planted leaving 5 feet land free from the wall in all four sides. It was also decided that the distance from one tree to another in both row and column will be 4 feet. What is the maximum number of trees that can be planted in the land?
(Geometry-Rectangle)Given, length = 90 feet and Breadth = 66 feet
Stimulated length of tree plantation = 90-(5+5)=90-10 = 80 feet
Stimulated breadth of tree plantation = 66-(5+5)=66-10=56 feet
The number of columns bc = [leaving 4 feet in rows and columns]
=20+1=21
And the number of rows be = [leaving 4 feet in rows and columns]
== 14+1=15
Maximum number of trees that can be planted = 21 15 = 315
