Question

If the breadth of a rectangle is doubled and length remains same , then its area will be :

• A. $\text{four times}$
• B. $\text{doubled}$
• C. $\text{three times}$

Answer 1

The correct option is B

$\text{doubled}$

We know that area of rectangle is $\text{=length×breadth}$

Let $\text{l}$ be the length and $\text{b}$ is the breadth

So according to the question $\text{l}$ be same and $\text{b=2b}$ then area becomes

$\text{area=l×2b=2lb}$

Hence area becomes twice the original area .

Therefore option(B) is the correct answer and all other options are incorrect .
