Answer:
900.
Step-by-step explanation:
1) the initial area is: A₀=0.5*base*h;
2) the final area is: A=0.5*(5*base)*(5*h).
It means, that 25A₀=A, then A=900 [cm²].
The answer is most likely a because if you calculate its better
Answer:
1.725 mph
There are 5280 feet in a mile, so you divide by that and get 12.075. Since it's seven hours, you divide by 7 and get 1.725.
A=LWH
divide both sides by LW
A/(LW)=H
