huh what's that that's like the second one of these I see
I think you basically just got to add everything up . I mean , i can already tell this is a graph question but it says perimeter so perimeter somehow means add everything up. But im still not too sure ..
Since it is given that one hole = 0,79m^2
0,79=3,142 x radius^2
radius^2=3,142 Divided by 0,79
radius=Square Root of 3.97721512
radius=1.994295662
=1.99m^2 (3 Significant Figures)
