Answer:
120m^2
Step-by-step explanation:
this is a pythagorean triple, which means that the three numbers form a right triangle. I recommend memorizing the most popular ones
So the area of this would just be 10m*24m/2 or 120m^2
I believe the answer is 40%
Not entirely sure, hope I helped though!
If Monica walks
1km...........................15min
?km............................60min

Monica walks 4km in 60 min(1H)
1km=1,000m
4km=4,000m in 1 hour
