उत्तर

Area of the rectangle = (Length × Breadth) sq.units

Area of the outer rectangle = (L × B) sq.units

Length of the outer rectangle L = 80 m

Breadth of the outer rectangle B = 50 m

Length of the inner rectangle l = 70 m

Breadth of the inner rectangle b = 40 m

Area of the outer rectangle = 80 × 50 m2 = 4000 m2

Area of the inner rectangle = l × b sq.unit

= 70 × 40 m2 

= 2800 m2

Area of the pathway = Area of the outer rectangle – Area of the inner rectangle

= 4000 – 2800 m2 

= 1200 m2

Area of the pathway = 1200 m2
