Answer 1

Answer:

The length of the rectangle is 21 cm

Step-by-step explanation:

Correct Question : The length and breadth of a rectangle are in the ratio 3: 1. If the breadth is 7 cm, then the length of the rectangle is:

Let,

• The breadth be x
• The length be 3x

Given,

• Breadth =  7cm

If x = 7 cm ,

Then,

3x = 3 × 7

= 21 cm

Therefore,

The length of the rectangle is 21 cm
