Answer 1

Answer:

Yes, the answer is the breadth of rectangle is 5 cm.

Step-by-step explanation:

perimeter of square=40 cm

side of square=perimeter/4

=40 cm/4

=10 cm

area of square=side*side

=10*10 cm

=100 sq. cm

breadth of rectangle=area/length

as we know that area of square is same as area of rectangle so area of rectangle will also be 100 sq. cm now breadth=100/20 cm

=5 cm that is how we can solve this sum.
