What is the perimeter of a rectangle of length $7\text{cm}$ and breadth $4\text{cm}$?

• A. $24\text{cm}$
• B. $28\text{cm}$
• C. $23\text{cm}$
• D. $22\text{cm}$

Answer 1

The correct option is D $22\text{cm}$

Length of the rectangle $=7\text{cm}$
Breadth of the rectangle $=4\text{cm}$​
Perimeter of the Rectangle $=2\times (\text{length}+\text{breadth})$
$=2\times (7\text{cm}+4\text{cm})$
$=2\times 11\text{cm}$
$=22\text{cm}$
