Answer 1

Answer:

Area of rectangle = 340 cm sq.

Its breadth =17 cm

As we know ,

Area of rectangle = length ×breadth

340=17 × breadth Therefore, breadth = 340/17

=20 cm

Now ,

Its perimeter = 2 ( length +breadth )

=2×(17+20)

=2× 37

=74 cm

So, 74 cm will be the perimeter of given rectangle .
