Question

The lengths of sides of a square is 5 cm. Find the
ratio of its perimeter to area.​

Answer 1

area of a square = a²

here a=5

so area= 5²

=25

perimeter= 4a

=4×5

= 20

ratio= 20:25

i.e. 4:5

Answer 2

Answer:

Step-by-step explanation:

Side of square = 5cm

Perimeter of square = 4 × side

=4 × 5cm = 20cm

Area of square = side × side

= 5cm × 5cm = 25 sq. Cm

Ratio of its perimeter to area = 20 : 25 or 4 : 5
