Question

the perimeter of a square is P . what is the length of its side. if the area is taken as A. write the relation between A and P​

Answer 1

Step-by-step explanation:

perimeter =P

let length of side be x

perimeter P=4x -----(1)

Area A=x^2 --------(2)

from (1) x=P/4

x^2 =P^2 /16

putting value of this x^2 in (2)

we get A = P^2 /16

P^2 =16A

Answer 2

4√A=P

Step-by-step explanation:

As given in question

4a = P. ...(I) (4a is perimeter)

area = A

therefore a=√A

putting the value of a in equation I

4√A=P
