40 sides
no, these are the first 20 triangle numbers: 1 3 6 10 15 21 28 36 45 55 66 78 91 105 120 136 153 171 190 210
The interior angle of a regular polygon with x sides is 180(x-2)/x. Rearranging the formula for x, the number of sides for a shape with y angles is 360/(180-y). From this formula, the number of sides is 40.
1 in = 0.0254m 171 in = 171 x 0.0254 m ~= 4.34m
