Question

Frame the equation from the informarion.The perimeter of a reactangle is 40cm.the length of rectangle is more than double its breadth by 2.(use x and y variable)​

Answer 1

Answer:

Given the perimeter of a rectangle is 40 cm

That means the sum of 2Breadth and 2length is equal to 40 cm

So before framing the equation see one thing

Given the length of the rectangle is double it's breadth by 2 That means

$2length = beadth + 2$

Let length =X

breadth =y

So the equation is

$= > 2 \times 2x + 2 \times( y + 2) = 40$

$= > 4x + 2y + 2 = 40 \\ = > 4x + 2y = 38$
