Advanced factorization​

You can always use the quadratic formula to find two roots of a quadratic trinomial. But often, you can find the roots more simply by factoring. Sometimes, you can even use factoring to find the roots of a higher-order equation, like a cubic or quartic polynomial.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
