The number in the ten thousand place must be multiplied by 10 compared to the number in the thousandth place. So in 22000 2 is multiplied by 10000 = 20000 and 2 is multiplied by 1000 = 2000.
I split it into parts. The small rectangle sticking out is 2x3 which is a 6 and the big rectangle 4x8 which is 32. The triangle is 8x2/2 which is 8. 6+32+8 = 46
