The answer is 940 1/2 by first you will have to add the length soo...
22 1/2 +25 is 47 1/2
But then you will have to 47 1/2 and 19 4/5 into a mixed number..
47 1/2 = 95/2
19 4/5 = 99/5
Then you multiply 95/2 and 99/5 and get 9405/10.After that then you will divide 9405 by 10 and you should get 940.5 which is also equal to 940 1/2 ft
Hopes this helps! ( ͡° ͜ʖ ͡°)
