Answer 1

Perimeter= 800 m

side of the square field =800/4 =200 m

cost =1.50* 40000

=60000 rupees

Done! :)

Plz mark as brainliest if it helped! Thanks..byee! :)))

Answer 2

Perimeter of square field = 800m = 4× side
Side of field = 800/4= 200m
Area of field = Side× Side
= 200× 200
= 40000m2
Cost of grassing = 40000× 2.50= ₹ 60000
