if the sides of a square are lengthened by 6cm, the area becomes 121cm^2. find the length of a side of the orginal square.

Weegy: If the original square side is x, x>0 => when it's lengthened it is x+6 S=x^2 S1 = (x+6)^2 = 121, => x^2+12x + 36 = 121, x^2+ 12x - 75=0, => x =-17 and x = 5, but x>0 Final answer: x = 5 (More)
