<h3>What is quadratic equation?</h3>Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.
Given that:
So for the triangle, the perimeter would be:
By solving in above equation, we get
So, we take x= 1.5 and neglect -4 because we can't take negative roots of the quadratic equation.
Hence, the value of x is equal to 1.5.
