Question

Find the side of square field whose perimeter is 1616 m

Answer 1

let the side of square be a
perimeter = 4a

4a = 1616
a = 1616/4
a = 404 m
the side of square is 404 m

Answer 2

Using the formula P=4/a                    {P is perimeter and a is side}
 a=P/4         
 a =1616/4
 a=404 m
