Question

b) The length of a rectangle is twice that of the width. The perimeter of the rectangle is
24 cm. What is the width of the rectangle?
​

Answer 1

Step-by-step explanation:

length= 2x

breath= x

perimeter of rectangle = 2(l+b)

= 2( 2x+x)

= 2(3x)

=6x

6x= 24cm

x= 4

breath is 4cm

Answer 2

Answer:

4 cm

Step-by-step explanation:

Let the breadth be b cm

let the length be 2b cm(twice of breadth)

perimeter = 2(l+b)

24 = 2(2b + b)

12 = 3b

b = 4
