Question

The length of a rectangle in twice its breadth . If the perimeter is 24 meters , find the length and breadth of the rectangle.​

Answer 1

Answer:

Let the breadth of the field = x cm ∴ its length = 2x and, its perimeter = 2 x (length + breadth) = 2 x (2x + x) = 2(3x) = 6x cm Perimeter = 60 cm

60 cm = 6x cm

x = 60/6 = 10 cm

Breadth = x cm = 10 cm

Length = 2x cm = 20 cm

Explanation:

so, answer is 10

Answer 2

$\huge\bf\fbox\red{Answer:-}$

Perimeter of rectangle

= 2(length + breadth)

Here it is given that length is twice of breadth

Let 'L' be the length and 'b' be the breadth then

It is given that L = 2b

And as per given information

2(L + b) = 24

We can replace 'L' with '2b' because it's twice of b

Then we will get

2(2b + b) = 24

2(3b) = 24

6b = 24

b = 24/6

$\bf\fbox{Breadth = 4 m}$

Therefore,

L = 2 × b

= 2 × 4 m

$\bf\fbox{Length = 8 m.}$
