Question

the length of a rectangle is twice its width. its perimeter is 56 units. find its length and width.

Answer 1

Answer:

Let the width be x cm.

Then length = 2x cm.

Perimeter = 2 ( l+b)

56. = 2 ( 2x + x )

56. = 2× 3x

56 = 6x

x = 9.33 cm

Length = 2 × 9.33 cm = 18.66 cm

width = 9.33 cm.

Answer 2

Step-by-step explanation

:Given data :- the length of a rectangle is twice it's width. And the perimeter is 56 cm .

Find out the length of the rectangle =?

We know that the perimeter P =56 cm

2(Lenght +W) =56

2(x+2x)=56

6x=56, x = (56/6)=9.33 cm. answer

So the width of the recatngle W =x = 9.33 cm
