Answer:

1)14  2)17.5  3) 60  4) 238 6)58.065

I forgot how to do fraction ones I'm sorry.

Step-by-step explanation:

1) A= (input formula)

2=4·7

2=14

2) A=(formula)

2=7·5

2=17.5

3) A=(input formula)  

2=12·10

2=60

4) A=( input formula)

2=34·14

2=238

6) A= (input formula)

2=4.9·23.7

2≈58.065
