Answer:
Area: T = 24
Perimeter: p = 24
Semiperimeter: s = 12
Explanation:
We know the lengths of all three sides of the triangle, so the triangle is uniquely specified.
a=6
b=8
c=10
The triangle perimeter is the sum of the lengths of its three sides
p=a+b+c=6+8+10=24
The semiperimeter of the triangle is half its perimeter. The semiperimeter frequently appears in formulas for triangles to be given a separate name. By the triangle inequality, the longest side length of a triangle is less than the semiperimeter.
Heron's formula gives the area of a triangle when the length of all three sides is known. There is no need to calculate angles or other distances in the triangle first. Heron's formula works equally well in all cases and types of triangles.
