Step-by-step explanation:

One of the side of rectangular region = 20 cm

Area of rectangular region = Length \times BreadthLength×Breadth

= 20 \times Breadth20×Breadth

We are given that The area of a rectangular region is 560 cm square

So, 20 \times Breadth = 56020×Breadth=560

Breadth = \frac{560}{20}Breadth= 20560

Breadth =28

Perimeter of rectangular field = 2(l+b)=2(20+28)= 96 cm

Hence its perimeter is 96 cm
