Question 1094463: The triangle below has a total perimeter of 450 cm:
picture of a triangle with sides 128 and 150. Third side unknown
Write an equation and solve it to find the length of the longest side of the triangle.
128x + 150 = 450; x = 2.34 cm
x + 278 = 450; x = 172 cm
2x + 278 = 450; x = 86 cm
150x + 128 = 450; x = 2.15 cm

The triangle below has a total perimeter of 450 cm:
picture of a triangle with sides 128 and 150. Third side unknown
Write an equation and solve it to find the length of the longest side of the triangle.
=================
Perimeter = sum of the 3 side lengths.
That's the same as the "total perimeter"
------------
a + b + c = 450
128 + 150 + c = 450
c = 172 cm
