Just ignore the pencil markings, anyone can explain how to do this question?

114 m.

Step-by-step explanation:

The perimeter of the whole pond = 2*21 + 2*12

= 66m.

The length of the sides of each square pond =  12 - 2(3) = 6 m.

So the perimeter of the 2 ponds is 2 * 4 * 6 = 48 m.

The total perimeter of the area planted with flowers = 66 + 48

=  114 m  (answer).
