Question
The figure shown is the aerial view of the pathway. Find the area of the pathway
Solution
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
