Problema Solution

A garden measuring 12 meters by 20 meters is to have a pedestrian pathway installed all around it, increasing the total area to 503.84 square meters. What will be the width of the pathway?.

Answer provided by our tutors

let 'x' represent the width of the pathway in meters


area = length * width


503.84 = (12+x)(20+x)

solving for 'x' we have a positive value of x=6.8


the width of the pathway will be 6.8 meters
