Question

The perimeter of the rectangle whose breadth is $6.5cm$ and length is double the breadth is :

• A. $26cm$
• B. $39cm$
• C. $19.5cm$
• D. $9.75cm$

Answer 1

The correct option is B

$39cm$

Given that , breadth of rectangle $=6.5cm$

length of rectangle $=2\times \mathrm{breadth}$

$=2\times 6.5=13cm$

As we know ,

Perimeter of rectangle $=2\times (\mathrm{length}+\mathrm{breadth})$

$=2\times (6.5+13)$

$=2\times 19.5$

$=39cm$

Thus, the perimeter of rectangle $=39cm$.

Hence, option (B) is the correct option.
