Question

the perimeter of rectangular piece of paper is 56 CM if the length is 3 times of its what is its width

Answer 1

Let the width be z
Then length = 2Z
ATQ

Perimeter of rectangle = 2(l+b)
→56= 2(3z+z)
→56= 2*4z
→z= 56/8
→z= 7cm

Breadth= 7cm
Length= 3z= 3*7= 21cm

Thank You....

Hope this will be helpful for you.

Answer 2

Step-by-step explanation:

Let the width be x

Then length = 2Z

Perimeter of rectangle = 2(l+b)

→56= 2(3x+x)

→56= 2*4x

→x= 56/8

→x= 7 cm

Breadth= 7 cm

Length= 3x= 3*7= 21 cm
