Answer:
x = 8.6603 m
Step-by-step explanation:
If x is the length of a side of the square, the area of the square will be x^2.
So, if the area of the square is 75 ft2, we can formulate the quadratic equation:
x^2 = 75
Now, solving the equation, we just need to make the square root of 75:
x = sqrt(75) = ±8.6603
x1 = 8.6603
x2 = -8.6603
Now, as x represents the length of a side of the square, and measurements can't be negative, we take only the positive value, so:
x = 8.6603 m
