ratio of side l:b = 7:5
let l = 7x cm
b= 5x cm
given perimeter = 96 cm
2(l+b) =96
l+b =96/2
l+b =48
7x+5x = 48
12x =48
x= 48/12
x= 4
therefore
l = 7x = 7*4 =28 cm
b= 5x= 5*4 =20cm
let l = 7x cm
b= 5x cm
given perimeter = 96 cm
2(l+b) =96
l+b =96/2
l+b =48
7x+5x = 48
12x =48
x= 48/12
x= 4
therefore
l = 7x = 7*4 =28 cm
b= 5x= 5*4 =20cm

Length(L) = 7x
Breadth(B) = 5x
Perimeter of rectangle = 2(L + B)
=> 2(7x + 5x) = 96
=> 12x = 96/2
=> 12x = 48
=> X = 4
Length of rectangle(L) = 7x
=> 7*4
=> 28 answer
