The perimeter of a square is 8cm. work out the area of the square.

A = 4cm^2

Step-by-step explanation:

The perimeter of a square is given by

P = 4s  where s is the side length

8 = 4s

Divide each side by 4

8/4 = 4s/4

2 =s

The side length is 2 cm

The area of a square is given by

A = s^2

A = 2^2

A = 4cm^2

All side lengths of a square are equivalent, so one of them can be represented by .

There are four sides on a square, so the perimeter is .

Divide both sides by .

The area of a square is .

Solve the exponent.

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function
