Problema Solution
A plot of land doubles in size by adding x meters to the length and x meters to the width of the land.
If the original plot had an area of 200 by 300 meters, what is the value of x?
Answer provided by our tutors
The area of the original plot is: 200*300
The area of the doubled plot is: (200 + x)*(300 + x)
(200 + x)*(300 + x) = 2*200*300
