Answer 2

O.O WAIToops wronggg question SORRY
change to this:

If the sides of a square are increased by 4cm, its area becomes 196cm^2. Find the length of the sides of the original square.

Answer 3

and explain the steps too thanks :D

Answer 4

Let the lengths of the sides of the original square be x cm
it's given that they are increased by 4 and then the area becomes 196 cm^2 so the sides become x+4
Area of square= \(side^2\)
so
\[(x+4)^2=196\]
Do you get this?
