Answer to Problem 8CFU

  Area = 6.44 u2

Explanation of Solution

Given information: The triangle a=2,b=7,c=8

Calculation:

Solve for s to use Hero’s formula so that you can solve for the area of the triangle.

  s=2+7+82

Simplify and solve for s

  s=8.5

Substitute s into Hero’s formula to solve for the area of the triangle.

  A=8.5(8.5−2)(8.5−7)(8.5−8)

Simplify and solve for A

  A=6.44Area = 6.44 u2
