Question

the length of a rectangle is twice that of the width .the perimeter of the rectangle is 24cm .what is the width of yhe rectangle

Answer 1

length =2×width

according to question

24=2 (l+b)
24=2l+2b
24=4b+2b (2b =l)
6b=24 (4b=2l)
b=4 cm

Answer 2

Width of the rectangle is 4 cm

Step-by-step explanation:

Let,

The width of rectangle = b

The length of rectangle = 2 x b

The perimeter of rectangle = 2 ( l + b )

                              24 cm  =  2 ( 2 x b + b)

                              24 cm = 6 b

                                    b = 24 cm / 6

                                    b = 4 cm

So, the Width of the rectangle is 4 cm
