Therefore, required quadratic equation is:

If a square has an area of 45 square units its side has a length of

units. Is that a perfect length? I don't know, but I know it's perfect for a square whose area is 45.
The commutative property pf addition is a+b=b+a
I think it’s D.y2 +xy+x+3y+2
(Sorry if I’m wrong)
