Here is Your answer

Step-by-step explanation:

of the cost of 1m is 40

and total cost is 2400

then to FIND the total number of m

we need to TAKE the perimeter because they told fencing.... fencing goes around the ground so it is perimeter

we should divide 2400 by 40.

so the perimeter is 60 m

lenght as given is 24 m

2 (24) =60

=60-48 = 12 .

So breadth is 12 METER
