Answer:
280000 Bricks
Step-by-step explanation:
Length = 450m
breath of the field = 250m
We have a built a wall around the field then we have to find the perimeter of the field
PERIMETER OF THE WALL =2(L+B)
=2(450+250)
=2*700
=1400m
1m wall requires =200 bricks
1400m wall requires =1400*200bricks
=280000bricks
So 280000 bricks should be purchased to built a wall around the field
