Answer:
C. 60
Step-by-step explanation:
From triangle ADB,
![|AD|^2+|BD|^2=|AB|^2](https://tex.z-dn.net/?f=%7CAD%7C%5E2%2B%7CBD%7C%5E2%3D%7CAB%7C%5E2)
![|AD|^2+16^2=20^2](https://tex.z-dn.net/?f=%7CAD%7C%5E2%2B16%5E2%3D20%5E2)
![|AD|^2=20^2-16^2](https://tex.z-dn.net/?f=%7CAD%7C%5E2%3D20%5E2-16%5E2)
![|AD|^2=400-256](https://tex.z-dn.net/?f=%7CAD%7C%5E2%3D400-256)
![|AD|^2=144](https://tex.z-dn.net/?f=%7CAD%7C%5E2%3D144)
![|AD|=\sqrt{144}](https://tex.z-dn.net/?f=%7CAD%7C%3D%5Csqrt%7B144%7D)
![|AD|=12](https://tex.z-dn.net/?f=%7CAD%7C%3D12)
From triangle ADC,
![|CD|^2+12^2=15^2](https://tex.z-dn.net/?f=%7CCD%7C%5E2%2B12%5E2%3D15%5E2)
![|CD|^2+144=225](https://tex.z-dn.net/?f=%7CCD%7C%5E2%2B144%3D225)
![|CD|^2=225-144](https://tex.z-dn.net/?f=%7CCD%7C%5E2%3D225-144)
![|CD|^2=81](https://tex.z-dn.net/?f=%7CCD%7C%5E2%3D81)
![|CD|=9](https://tex.z-dn.net/?f=%7CCD%7C%3D9)
The perimeter is the distance around the figure.
The perimeter
![=15+20+16+9](https://tex.z-dn.net/?f=%3D15%2B20%2B16%2B9)
![=60](https://tex.z-dn.net/?f=%3D60)

Answer:
The actual area of the field in square kilometers is ![30000000 km^2](https://tex.z-dn.net/?f=30000000%20km%5E2)
Step-by-step explanation:
Scale : 1 cm = 50000 km
Area of field on map = ![1.2 cm^2](https://tex.z-dn.net/?f=1.2%20cm%5E2)
Now , 1 cm = 5000 km
![1 cm^2 = (5000 km)^2](https://tex.z-dn.net/?f=1%20cm%5E2%20%3D%20%285000%20km%29%5E2)
We are supposed to find the actual area of the field in square kilometers.
So, the actual area of the field in sq. km =![1.2 \times (5000)^2](https://tex.z-dn.net/?f=1.2%20%5Ctimes%20%20%285000%29%5E2)
Actual area of the field in sq. km ![=30000000 km^2](https://tex.z-dn.net/?f=%3D30000000%20km%5E2)
Hence the actual area of the field in square kilometers is ![30000000 km^2](https://tex.z-dn.net/?f=30000000%20km%5E2)
Answer:
$69.17
Step-by-step explanation:
.065 x 64.95 ≈ $4.22
$69.17 + $4.22 = $69.17
Brainliest would be appreciated but not required :)
