Answer 1

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

Answer 2

Answer:

Step-by-step explanation:

l=length=x

b= breath=y

formula is 2(l+b)

2(x+y)=20 its the mathematical form
