• A. $22cm$
• B. $28cm$
• C. $36cm$
• D. None.

Answer 1

Answer: (A)

$22cm$

Given that, the sides of a rectangle are $4cm$ and $7cm$.

To find out: The perimeter of the rectangle.

We know that, the perimeter of a rectangle is $2(l+b)$.

Hence, the perimeter of the given rectangle $=2(4+7)$

$\Rightarrow 2\times 11=22cm$

Hence, the perimeter of rectangle whose sides are $4cm$ and $8cm$ is $22cm$.
