Q4 of 58 Page 44

Let us express the following statements into linear equations in two variable and draw the graph of the equations.

The perimeter of out rectangular yard is 80m.

Let sides of rectangle are x and y.


Given Perimeter is 80m.


We know that perimeter of the rectangle = 2(sum of sides)


2x + 2y = 80


⇒ x + y = 40


Putting different values of x, we get different values of ‘y’, hence we get points for plotting as:
