Answer: A = 112km^2
Explanation:
A = L x W
A = 14km x 8km
A = 112km^2
The distance between two points can be found using the Pythagorean Theorem...
d^2=(x2-x1)^2+(y2-y1)^2
d^2=(-8-12)^2+(18-6)^2
d^2=400+144
d^2=544
d=√544 units
d=4√34 units
d≈23.3 units (to the nearest tenth of a unit)
A common denominator would be 24
