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
The triangle Inequality Theorem states that if the longest side is shorter than the sum of the other 2 sides, it will form a triangle.
7< 4 + 5 so it forms a triangle.
It is a scalene triangle (all 3 sides are not equal).
It makes an obtuse triangle. (To see why, click here: http://www.1728.org/triantest.htm )
In order for us to easily answer this problem, let us make the units uniform. So 1 kiloliter is equivalent to 10 hectoliters. This would mean that 11 kiloliters is 110 hectoliters. Since 40 hectoliters is for making ice cream, only 70 hectoliters of milk is left to be used in other ways. Hope this answers your question. Have a great day!
