White Square: 4 times 4 = 16 units squared.
Yellow Rectangle: 5 times = 20 units squared.
Red Rectangle: 3 times 4 = 12 units squared.
Purple Parrelogram: 10 times 2 = 20 units squared.
Green Parrelogram: 9 times 2 = 18 units squared. Orange Trapezoid: 1 times 7 = 7 divided by 2 = 3.5, 1 times 6 = 6 divided by 2 = 3, 1 times 1 = 1, 6+3.5+1= 10.5 units squared.
Blue Trapeziod: 1 times 2 = 2 divided by 2 = 1, 1 times 2 = 2 divided by 2 = 1, 1 times 2 = 2, 1+1+2= 4 units squared.
Gray Triangle: 2 times 4 = 8 divided by 2 = 4 units squared.
Area of the whole shape: 16+20+12+20+18+10.5+4+4= 104.5 units squared.
