Solve triangle abc if a 32 d 24 and c 18 also find the are

Solve triangle abc if a = 32, d = 24 and c= 18 also find the area of triangle abc. given that a = 7 at b = 15st and c = 12at find the area of the triangle. a pilot is flying from salt lake city to denver a distance of about 500 miles.

Solution

1)

a=32,b =24,c=18

s=1/2(a+b+c) = 37

area = sqrt(s(s-a)(s-b)(s-c)) = sqrt(45695) = 213.76

2)a =7,b=15,c =12

s = 1/2(7+15+12) = 17

area = sqrt(17*10*2*5) = 41.231

3)

total distance = 500 +2(150) = 800
