adding a shrinkage/ growth

plot_polygon = @(x,y) plot(polyshape(x,y));
x0 = -10;
y0 = -4;
x_plane = [0,1,1.5,2,2.5,2.5,1.5,3,4,4,0]+x0;
y_plane = [0,1,1,-1,-1,1,1,1,2,0,0]+y0;
plane = polyshape(x_plane,y_plane);
t1 = translate(plane,[20,0]);
t2 = translate(plane,[0,8]);\
plot_polygon(x_plane,y_plane)
hold on
plot(t1)
plot(t2)
holf off

That is all my code. if you run it you get a shape the that shape is translated 2 times. im trying to make it so it grows horizontally by 2.4% when moving in the x direction

See also: cant seem to get this to translate and translating this polygon to a new position neither of which was either followed up or Accepted.

this relates to the growth of the problem
