Answer:
The length of the river on a map is ![9.6\ cm](https://tex.z-dn.net/?f=9.6%5C%20cm)
Step-by-step explanation:
we know that
The scale of the map is ![1:5,000,000](https://tex.z-dn.net/?f=1%3A5%2C000%2C000)
That means
1 cm on a map is 5,000,000 cm on the actual
or
1 cm on a map is 50 km cm on the actual
so
using proportion
![\frac{1}{50}\frac{cm}{km}=\frac{x}{480}\frac{cm}{km}\\ \\x=480/50\\ \\x=9.6\ cm](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B50%7D%5Cfrac%7Bcm%7D%7Bkm%7D%3D%5Cfrac%7Bx%7D%7B480%7D%5Cfrac%7Bcm%7D%7Bkm%7D%5C%5C%20%5C%5Cx%3D480%2F50%5C%5C%20%5C%5Cx%3D9.6%5C%20cm)

Step-by-step explanation:
Answer:
24 ft^2
Step-by-step explanation:
<u>Triangle:</u>
A = 1/2bh
A = 1/2*8*8
A = 1/2*64
A = 32 ft^2
<u>Rectangle</u>:
A = lw
A = 4*2
A = 8 ft^2
<u>Triangle - Rectangle:</u>
A = 32 - 8
A = 24 ft^2
