Question

The length and breadth of a rectangle are 20 cm and 10 cm respectively. What is the ratio of length of the rectangle to its area?

• A. 1 : 20
• B. 1 : 3
• C. 1 : 10
• D. 1 : 2

Answer 1

The correct option is C 1 : 10

We know,
Area of a rectangle = $l\times b$
= $20\times 10$
= 200 sq cm

$\therefore$ The required ratio $=\frac{20}{200}=\frac{1}{10}$
$\Rightarrow$ 1 : 10
