I REALLY NEED HELP PLEASE

Model the following problem with a quadratic equation. Then solve. Find the length of a side of a square with an area of 12 ft^2. Model the problem with a quadratic equation. Let x be the length of a side of the square.

Answer 1

The area of a square = one side multiplied by an adjacent side. As all sides are equal the equation is
x^*x = 12
or x^2 = 12

Solving
x = sqrt 12
= 2 sqrt3
= 3.46 ft correct to the nearest hundredth
