Question

The length of a rectangle having a perimeter of $22$ cm is $7$ cm. What will be its breadth?

• A. $4$ cm
• B. $5$ cm
• C. $6$ cm

Answer 1

The correct option is A $4$ cm

We have a rectangle with perimeter of $22$ cm and length of $7$ cm.


Since, the rectangle has opposite sides equal,
the perimeter which is the sum of all four sides will be

$=7+h+7+h=22$

$=14+2h=22$

$=2h=22-14=8$

$=2h=8$

Dividing both sides be $2$

$h=4$ cm

So, the breadth of the rectangle is $4$ cm
Option 'a' is correct.
