The perimeter of a triangle is 240. Its sides are proportional to 3:4:5. The largest side of the triangle is ?

1 answer:

3 0

If the sides are proportional you can use the formula:

3x + 4x + 5x = 240 and solve for x.

which is: 12x = 240
x = 20

The longest side is 5x, so the longest side is 100.
