Question

Consider a rectangle of length 12 cm and breadth 2 cm.Then the perimeter of this rectangle is

• A. 38 cm
• B. 32 cm
• C. 28 cm
• D. 24 cm

Answer 1

The correct option is C

28 cm

If '$l$' is the length of the rectangle and '$b$' is its breadth, then its perimeter is given by

$P=l+b+l+b=(2\times l)+(2\times b)$

Given $l=12\text{cm}$ and $b=2\text{cm}$

Then, perimeter of the given rectangle is,

$P=(2\times 12)+(2\times 2)=24+4=28\text{cm}$
