Question

frame the linear equation in two varbles for ' the perimeter of a rectangle is 40cm​

Answer 1

Answer:

(l+b) = 20

Step-by-step explanation:

perimeter of rectangle = 2(l+b)

given perimeter = 40 cm

therefore,

2(l+b) = 40

(l+b) =40/2

(l+b) = 20

Answer 2

$\huge\mathfrak\blue{Question}$

Frame the linear equation in two variables for the perimeter of a rectangle is 40cm.

Answer

✔ So we know that perimeter of rectangle is 2(l+b)

✔ Here in above question the perimeter is given as 40cm.

____________________

★ So let the length be A and breadth be K

★ 2 ( A + K ) = 40cm

★ 2A + 2K = 40 cm

❥The linear equation in two variable will be 2A + 2K = 40cm.

====================

• The other linear equation can be formed as A + K = 20cm
