rectangular field are in the ratio 9:7
So length = 9x
Breadth = 7x
Perimeter = 144 m
2(l +b ) = 144
9x +7x =144 / 2
16 x=72
X =72/16
X =4.5
L =9x
= 9 *4.5
40.5 m
B = 7x
7*4.5
= 31.5 m
So length = 9x
Breadth = 7x
Perimeter = 144 m
2(l +b ) = 144
9x +7x =144 / 2
16 x=72
X =72/16
X =4.5
L =9x
= 9 *4.5
40.5 m
B = 7x
7*4.5
= 31.5 m
