Question

14. The length of a rectangle is twice the breadth. If its perimeter is 60 m, then find its length​

Answer 1

Answer:

LENGTH = 20 M

BREADTH = 10 M

Step-by-step explanation:

B = X

L = 2X

6X = 60

X = 10

Answer 2

Answer:

The Value of length is 20 m .

Step-by-step explanation:

Given -

The length of a rectangle is twice the breadth.

The perimeter rectangle is 60 m

To find -

The length

Solution -

Let ,

Breath is $x$

∴ Length is $2x$

As, we know that

$P=2(l + w)$

Where ,

p = perimeter

L = Length

W = breath

Put given value in the formula,

$60= 2(2x+x)$

$60 =2(3x)$

$60 =6x$

Divide both side by 6 we get

$x=10$

Put the given value of x

Breath is $x$ = $10$ m

Length is $2x$ = $2\times 10$ = $20$ m

The Value of length is 20 m .
