Question

A rectangular field is 20 long and 14 m wide there is a path of equal width all aroud it having an area of 111 sq.m find width of path

Answer 1

Square meters enclosed by path = 111 m^2 
(Length of path) X (width of path) = 111 m^2 
Let W = width of path 
Length of path = 2(20) + 2(14) + 4W 
(40 + 28 + 4W) X (W) = 111 
(4W^2) + 68W = 111 
4W^2 + 68W - 111 = 0 
W = 1.5 m
hope this helps you.
