Problema Solution
A garden measuring 12 meters by 19 meters is to have a pedestrian pathway installed all around it, increasing the total area to 521.36 square meters. What will be the width of the pathway?
Answer provided by our tutors
let 'x' be the width of the pathway then
since the area of the rectangle is width * length we have
(12+ x)*(19 + x) - 12*19 = 521.36
by solving we find
x = 12.0973 meters
we consider only the positive solution of the equation.
the width of the pathway will be 12.0973 meters.
