Question ) the side of a rectangular field are in the ratio 7:9 and the parameter is 288 metres. find the side of the field.
★ Answer .) Let , the ratio of length is to breadth be 7 : 9
Length = 7x
Width = 9x
Perimeter = 288 meter
=> Perimeter = 2( l + w )
→ 2 ( l + w ) = 288
→ 2 ( 16 x ) = 288
→ 16x = 144
→ x = 9
Length = 7x = 63 meter
Width = 9x = 81 meter

Let us take the given ratio be 7x:9x.
Therefore it's perimeter = 2(l+b).=2(7x+9x)=2×16x = 32x.
So
Atq . 32x=288
or. x. =288÷32
Therefore x= 9
Therefore 1st side = 7x =7×9=63m.
Therefore 2nd side = 9x =9×9=81m.
