Answer:
Step-by-step explanation:
I think it's 64
Answer:
2 should be the correct one.
Answer:
20*30km = 600km
15*30km = 450km
600km * 450km = 270000 km^2
Step-by-step explanation:
assuming 1cm --- 30km causes that 2cm --- 60km, 3cm --- 90km, 4cm --- 120km etc. Notice that number of km's is 30 times greater than the number of cm's on a map
using this logic, you calculate both real dimensions of Colorado by multiplying 20*30 = 600 km and 15*30 = 450km
Then we use a formula of an area of a rectangle
assuming
and get
which is an actual area of Colorado
Assuming the figure has identifiable bases and sides, the total surface area is the sum of the areas of those:
... B. Base area + lateral area
First we have to find how much water leaked
5galllons-3 gallons=2 galllos of water leaked
Now we know

Finally we can simplify it

- its the answer
