Question

perimeter of square field is 72 metre find its sides and hence find the area​

Answer 1

Step-by-step explanation:

perimeter=4a

72=4a

72/4=a

18=a

area of square=a*a

= 18* 18

= 324

$= 324cm {}^{2}$

Answer 2

Answer:

side is 18m and area is 324 cm ²

Step-by-step explanation:

perimeter=72cm

and perimeter is 4*side

4*side=72

side=72/4

so,side=18cm

area of square =side *side

so area =18*18

=324cm²
