Question

The perimeter of rectangle is 36 cm. What is the breadth, if the length is twice the breadth?​

Answer 1

Answer:

hi

Step-by-step explanation:

the answer is

so first we will divided =2×(l+b)

36 =(l+b)

36/2 =16

the length is twice so =16+16

=32

Answer 2

$\sf\blue{Given\: :}$

Perimeter of a rectangle = 36cm.

$\sf\pink{Find\: :}$

Length and breadth of a rectangle = ?

$\sf\purple{Solve\: :}$

Let the breadth be = x cm

If, length is twice the breadth so it will be = 2x cm

A/Q -

Perimeter of a rectangle = 2(length + breadth)

36 cm = 2(2x + x)

36 cm = 2(3x)

36 cm = 6x

x = $\frac{36}{6}$

x = 6 cm.

So, breadth of rectangle = x = 6cm.

And length of a rectangle = 2x = 2 × 6 = 12cm.

Formula Used :

Perimeter of a rectangle = 2 × ( l + b).
