8w=40
You get area by doing length x width. In this case, the “length” is the height. So you would need to figure out what you multiply 8 by to get 40.
Answer:
The answer is 400
Step-by-step explanation:
<u>solution</u>
W=f×d×cos theta
=25N×16m×cos 45°
=400Nm×cos 45°
=282.84J
=25N×7m×cos 10°
=175Nm×cos10°
=172.34J
Total workdone=282.84J+172.34J=455.18J
