A rectangle with its 4 corners removed.
Each of the 4 identical corners removed is a quarter circle.
Ratio of length to the breath of the rectangle is 12:5
It is 17 cm between the 2 removed corners at the length of the Rectangle
It is 3 cm between the 2 removed corners at the breadth of the Rectangle
What is the radius of each quarter circle?
:
let r = the radius of the circle
%2817%2B2r%29%2F%283%2B2r%29 = 12%2F5
cross multiply
5(17+2r) = 12(3+2r)
distribute
85 + 10r = 36 + 24r
85 - 36 = 24r - 10r
49 = 14r
r = 49/14
r = 3.5 cm is the radius

Check; 2r=7: length 17+7; width 3+7
24%2F10 = 12%2F5
