Just a moment, please.

40x40x3=4800 (square centimeter)

65x40x2=5200 (square centimeter)

Red: /5200+4800= 10000 (square centimeter)/

40x(65- 10)=2200 (square centimeter)

65x40= 1300 (square centimeter)

40x40= 1600 (square centimeter)

2200+1300+1600 = 5100 (square centimeter)

5 100x2= 10200 (square centimeter)

Yellow:/10000 =10200 = 20200 (square centimeter)/
