Problema Solution
if the sides of a square are lengthened by 8 cm, the area becomes 289 cm^2. find the length of a side of the original square
Answer provided by our tutors
the original length of the square side's is 9cm.
u may reach this solution by considering the original side as x (variable)
area of the square is s^2 where s is the side length = x+8
then (x+8)^2=289
taking the square root of both sides then x+8=17
then x=17-8=9cm
