You're right.
By the way, the solutions of your your quadratic equations are:
x = - 31 / 2 and x = 3 / 2
Length can not be negative so x = 3 / 2 = 1.5 m
A garden is measuring 12m by 16m is to have a path around it, increasing the total area to 285 square metre. what is the width of the path?
I went like that
(16+2x).(12+2x)= 285
4x^2+56x-93=0
I am stuck now
