The breadth of a rectangular field is 60% of its length . If the perimeter of the field is 800 m, what is the area of the field ? Correct Answer 37500 sq.m
Let, length = 100x meter, breadth = 60x meter Perimeter = 2 ( length + breadth) 800 = 2 ( 100x + 60x) 800 = 320x x = 5/2 area = ( 100 × 5/2) × ( 60 × 5/2) = 37500 sq.metre
