Question

A path 2.5 metres wide is running around a square field whose side is 45 metres determine the area of the path

Answer 1

width of the path =2.5m
side of the square fields=45m=45/2=22.5m=radius r of the square radius of the outer path with the width 2.5m
=22.5+2.5=25m
area of the path A=Area of the outer path -area of the square
A=pir^2-s^2
A=(22x25x25/7)-(22.5)^2
A=13750/7-506. 25
A=1964.29-506.25
A=1458.04sq.m
