What is the measure of the third side of a triangle where the perimeter is 8X plus 4Y and the others are X plus 2Y and 3X plus Y?
The perimeter of the triangle is 8x + 4y. The measures of two of the sides are x + 2y and 3x + y. If these two sides were added together, they would be 4x + 3y:
x + 2y
3x + y
4x + 3y
The third side is the perimeter minus the two known sides, so 8x + 4y - (4x + 3y). Distribute the negative: 8x + 4y - 4x - 3y. This is equal to the third side, which is 4x +y.

How do you find the perimeter of a triangle if 10m and 25m are the given sides?
The lengths of two sides are not enough to determine the perimeter of a triangle: Either the third side or else the angle between the two given sides is also needed. If two of the sides are 10m and 25m, then the third side can be anything between 15m and 35m, and the perimeter can be anything between 45m and 70m.
What is formula of finding the perimeter of a triangle?
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
If two sides of the triangle is 6 and 5 what is the perimeter of triangle?
To find the perimeter of a triangle, you need to add the lengths of all three sides. If two sides of the triangle are 6 and 5 units long, you still need to know the length of the third side to find the perimeter. Without the length of the third side, it is not possible to calculate the perimeter of the triangle.
