Question

A path 3.5 m wide runs inside along the boundary of a square field whose side is 55 m .Find the area of the path .also find the cost of manuring the rest of the field at the rate of rs.23 per square metre

Answer 1

hi,

here's ur answer frnd...

given:-

length of the side of field=55m

area of the field=side×side

=55×55

=3025m²

length of the path=55-(3.5+3.5)

=55-7

=48m

area of remaining field=48×48

=2304

thus, area of the path=3025-2304

=721m²

hence, area of the path is 721m².

total cost of manuring the remaining part of field if per m² costs ₹23=2034×23

=₹52992

hope this helps u...

Answer 2

Step-by-step explanation:

Answer:

→ Area of the path = 861 m² .

Step-by-step explanation:

Given :-

→ Width of path = 3.5 m .

→ Side of square park along with path = 65 m .

To find :-

→ Area of the path .

Solution :-

∵ Side of square park without the path = 65 - ( 2 × 3.5 )  =  58 m .

Now, area of square park alnog with path

= side × side .

= ( 65 × 65 ) m² .

= 4225 m² .

And, area of square park without path

= side × side .

= ( 58 × 58 ) m² .

= 3364 m² .

Therefore, area of the path = ( 4225 - 3364 ) m² .

= 861 m² .

And, cost of measuring the rest of the field = 3364 × 25 .

= ₹86100 .

Hence, it is solved .
