If a square has an area of 25 sq cm, then it's side must be 5 cm. 5cm x 5 cm = 25 sq cm. A square has four sides of equal length, therefore 5 cm x 4 sides = 20cm.
The perimeter is 20 cm.

The area of a square = l^2 where l is the length of a side (all sides are by definition equal in a square). Perimeter of a square is 4.l and so we have
l^2 = 25 sq.cm l = sqrt.25 = 5 cm
Perimeter = 4.l = 20 cm

Length of side = 5 cm
Perimeter = 4 x 5 cm = 20 cm

area of square = a^2 = 25
a= sq root of 25
= 5 cm
Perimeter = 4a
= 4*5
=20 cm

since it doesn't say it has height I assume flat piece. area is l x w so 25 is 5 x 5. perimeter would be 4 total sides so which is 5 x 4 so perimeter should be 20.

5 times 4, that is 20 cm!

If the area is 25, therefore, you should get the measure of its side. 25/5=5. 5 is the measure of a side. Then, multiply 5 by 4(number of sides) and you will get the answer. So, the answer is 20cm.
