If two Adjacent sides of rectangle are in ratio 11:10 Then two Adjacent sides will be 11x and 10x. Putting these values in formula of Perimeter of rectangle i.e
P=2(l+b), Where 11x is length and 10x is breadth, Then
P=2(11x+10x), But the Perimeter is given then
84=2(11x+10x)
84=2(21x)
84=42x
x=3cm
Putting Value of x in Length and breadth we get
L=33cm and B=30cm
