Answer 2

As per the data given in the question,

We have to determine the value of breadth of the rectangle.

As per question,

It is given that,

Perimeter of rectangle = 80 cm

Length of rectangle = 28 cm

As we know that,

Perimeter of rectangle $=2(l+b)$

So, putting the value given in the question in the above formula,

We will get,

$80 = 2(28+b)\\=>28+b = \frac{80}{2}\\=>28+b = 40\\=>b = 12\:cm$

Hence, value of breadth of the rectangle will be 12 cm.
