The area of a square can be quadrupled by increasing the side length and width by 4 inches. what is the side length?

Let the original side of the square be x inches.When sides are increased by 4 inches the sides are x+4 inches.

Area of square with side x inches=

Area of square with sides x+ inches=

According to question:The area of a square can be quadrupled by increasing the side length and width by 4 inches.\

Or

Expanding we have:

Or,

Factoring,

(3x+4)(x-4)=0

3x+4=0   or  x=4

x= Or x=4.

Sides can not be negative so x=4.

The sides of the square will be 4 inches.
