(a) For the triangle
Area shaded = 1*h*.5 Total Area=4*h*.5
%age = 25% (after manipulations)
second figure Area shaded = 0.5*1*h
Total area = 4*h
%age = 12.5%
Third figure: one of the diagonals bisects the other in a kite. Look at the figure and you'll know which one. Let the equally bisected sides be called h
Shaded area=0.5*3*h
Total area = 2(0.5*4*h)
%age u do it
