Question 186885: A square field had 5m added to its length and 2m added to its width. The field then had an area of 130m^2 (to the second power. Find the length of a side of the original field. Answer by uday1435(57) (Show Source):
You can put this solution on YOUR website! Let x be the original side
New length = x+5, new width = x+2
New area = (x+5)(x+2) = 130
Means x^2 + 7x + 10 = 130; x^2 + 7x – 120 = 0, (x + 15)(x – 8) = 0
Answer: So the original length was 8 meters
