Understanding Area and Dimensions

The video tutorial by Anil Kumar addresses a geometry problem involving a rectangular lawn. The problem is to find the width of a uniform strip removed from the lawn, leaving 60% of the original area. The tutorial involves setting up and solving a quadratic equation using the quadratic formula. The solution process includes calculating the original and remaining areas, forming the equation, and applying the quadratic formula to find the width of the strip. The final answer is approximately 2.1 meters, with a restriction that the width must be less than or equal to 7.5 meters.

What are the dimensions of the original lawn?

• 20 meters by 10 meters

• 25 meters by 15 meters
