Let us construct the quadratic equations in one variable from the following statements.

There is a road of equal width around the outside of a rectangular playground having the length 45 m. and breadth 40 m. and the area of the road is 450 sqm.

Let the width of road be w m

area of road = area of rectangular paths + 4 squares at the corner.


So,





Hence the required equation is
