Problema Solution
A rectangular garden measuring 16 by 14 meters has its area increased by 216m^2 with a uniform width on all sides. What is the width??
Answer provided by our tutors
let x = the width by which the sides are increased, x>0
16 + x = the new length
14 + x = the new width
the area increase is 216 m^2
(16 + x)(14 + x) - 16*14 = 216
by solving we find
x = 6 m
