Answer:

42, 24

Step-by-step explanation:

Let the real length and breadth be 7x and 4x respectively.

Now fencing is done on the boundary so the total fencing will be = perimeter and total distance that has been fenced = 3300/25=132

Now perimeter =2(length+breadth)

=2(7x+4x)

=2(11x)

= 22x

Now 22x=132

so x=(132/22)

x=6

Now dimensions are 7×6 ,4×6 = 42 , 24
