Hi,

The area of rectangle garden is 200 square meters. 

The length of the garden is 1 meter more then 3 times its width 'x'

width 'x', length (3x+1)



A = l%2Aw+=+%283x%2B1%29x+=+200m%5E2

    3x^2 + x - 200 = 0

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

x+=+%28-1+%2B-+sqrt%28+2401+%29%29%2F%286%29+

x+=+%28-1+%2B-+49%29%2F%286%29+

    x = 8m   (tossing out negative solution for unit measure)

width is 8m   and length is 25m    %283%2A8%2B1%29

 8m%2A25m+=+200m%5E2
