Given :

Ratio of the length and breadth of rectangle = 3: 1

Let the length be 3x

And let the breadth be X

Step-by-step explanation:

If X = 7cm

Length = 3x

3x = 3× 7

= 21cm

hence, The length of rectangle is 21cm

Answer 2

ANSWER :

The length and breadth of a rectangle are in ratio 3 : 1.

Let,

The length of rectangle = 3x

The breadth of rectangle = 1x = x

It is given that the breadth of rectangle is 7 cm

So, we can conclude that, breadth (x) = 7 cm

Now, we can find the length of the rectangle by putting the value of x, i.e., 7

Length of the rectangle = 3x = 3 × 7 = 21 cm

$\implies$ Hence, the answer is 21 cm.
