2 answers:
Answer:
P = 28 cm
Step-by-step explanation:
The area of a square is
A = s^2 where s is the side length
49 = s^2
Taking the square root of each side
sqrt(49) = sqrt(s^2)
7 =s
Now find the perimeter of the square
P = 4s
P = 4(7)
P = 28 cm
Answer:
The perimeter of square is 28 cm.
Step-by-step explanation:
- To find perimeter of square firstly we need to find the side of square.
using Formula
Area of square = ( side )²
taking square root of both side
- √49cm² = √side²
- 7 cm = side
Now,
<u>Perimeter of square is</u>
Perimeter of square = 4 × side
multiply,
Hence , the perimeter of square is 28 cm.
