Question

Length and breadth of field is 450m and 250m . a wall is to be built around the field. one metre length of wall requires 200 bricks.how many bricks should be purchased

Answer 1

doed see
length,breath of the field=450m,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 .......

Answer 2

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
