Question

the perimeter of a rectangle is 40 cm. write the information in mathematical form using two variables

Answer 1

Step-by-step explanation:

As the perimeter is 40 cm, length is 2b + 2 cm and breadth is b cm therefore, we have 40 = 2(2b + 2 + b). This results into 40 = 2(3b + 2) and we can further write this equation as 40 = 6b + 4.

Answer 2

Step-by-step explanation:

Given, perimeter of reactangle=40

we know, Perimeter of reactangle=2(l+b)

40 =2(l+b)

20=l+b
