    Given length of is 50 meters and 42 meters broad and Inside rectangular lawn 6 m width

    Then area of Lawn in length sides of rectangle=2×lengthofrectangle×widthofpath=2×50×6=600 sq m

    And the  of Lawn in width sides of rectangle=2×(widthofrectangle−2widthofpath)×widthofpath=2×(42−2(6))×6=2(42−12)6=60×6=360 sq m
