Question

The side of a square field is 20m. The space required to plant a tree is 2m squire how many trees can be planted in the field

Answer 1

Total area of square field=40m²
Area occupied by each tree=2m²
Therefore, no of trees=40/2=20

Answer 2

Given,
side =20m
space required to plant a tree=2 sq m
area of the field =20*20=400sq.m(area of a square = side *side )
no of plants can be planted =area of the field / space required to plant a tree
                                               =400/2=200 plants
