Perimeter of rectangular grassy plot=2(length+breadth)
189=2(l+10.5)
189=2×l+21
189-21=2×l
168/2=l
84=length
Area=length×breadth=84×10.5=882 m²

Perimeter=189m
the length of the rectangle = 2(length+breadth)
let length be x
2.x+10.5
x=10.5/2
   =5.41m
area of the rectangle = length x bredth
                                =10.5x5.41
                                 =56.81m
