Question

The perimeter of a square is 18 (2÷5) . What is the area

Answer 1

perimeter of square = 4* side

18*0.4=4* side

: •side= 7.2/4

side=1.8

now area of square=side^2

= 1.8^2

=3.24

hence the area of square is 3.24

Answer 2

perimeter =18(2÷5)

=7.2

side = 7.2÷4

=1.8

area = 1.8 ×1.8

= 3.24

hope it is help full
