Answer 1

To Find :

The area of green shaded region in given image.

Solution :

The area of green shaded region is given by :

Area = Area of outer square - Area of inner rectangle

Area = x² - ( x - 20)×( x - 25 )

Area = x² - ( x² - 25x - 20x + 500 )

Area = 45x - 500

Hence, this is the required solution.
