Question

Find the perimeter of the rectangle whose length is $3.6\text{m}$and breadth is $2.6\text{m}$.

• A. $10.4\text{m}$
• B. $12.4\text{m}$
• C. $11.4\text{m}$
• D. $13.4\text{m}$

Answer 1

The correct option is B

$12.4\text{m}$

Finding the perimeter of the rectangle

It is given that length of the rectangle is $3.6\text{m}$and breadth of the rectangle is $2.6\text{m}$

We know that perimeter of the rectangle $=2\left(\text{length +breadth}\right)$

So, perimeter of the given rectangle $=2(3.6+2.6)$

$=2\times \left(6.2\right)$

$=12.4\text{m}$

So, perimeter of the given rectangle is $\mathbf{\text{12.4 m}}$

Hence, option $\text{B}$ is correct.
