Answer:
Area of the triangle covered by the cars = 910.45 square km
Step-by-step explanation:
Since, all the sides of triangle ABC are given,
And formula for the area of a triangle with all sides given is,
Area = ![\sqrt{s(s-a)(s-b)(s-c)}](https://tex.z-dn.net/?f=%5Csqrt%7Bs%28s-a%29%28s-b%29%28s-c%29%7D)
Here, s = ![\frac{a+b+c}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%2Bb%2Bc%7D%7B2%7D)
And a, b, c are the measures of the sides of the triangle.
If a = 39 km, b = 87 km and c = 58 km
s = ![\frac{39+87+58}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B39%2B87%2B58%7D%7B2%7D)
s = 92
Therefore, (s - a) = 92 - 39
= 53
(s - b) = 92 - 87
= 5
(s - c) = 92 - 58
= 34
Now area of the triangle ABC = ![\sqrt{92(53)(5)(34)}](https://tex.z-dn.net/?f=%5Csqrt%7B92%2853%29%285%29%2834%29%7D)
= ![\sqrt{828920}](https://tex.z-dn.net/?f=%5Csqrt%7B828920%7D)
= 910.45 km²
Area of the triangle covered by the cars = 910.45 square km
Answer:
28
Step-by-step explanation:
1) subtract 12 from both sides
2) divide by negative 1
