Step-by-step explanation: Length of rectangle is x cm and breath is y cm. l×b = perimeter of rectangle x × y = 20 cm x = 20/y cm Putting the value of x x × y = 20 cm 20/y × y = 20 y = 20/20 y = 1 Now, value of y is 1 cm 1 × x = 20 cm x = 20 cm Reply

Answer: Step-by-step explanation: l=length=x b= breath=y formula is 2(l+b) 2(x+y)=20 its the mathematical form Reply

Step-by-step explanation:Length of rectangle is x cm and breath is y cm.
