The lengths of the sides of a triangle are 2: 4: 5. Find the lengths of the sides of a triangle similar to the given one if its perimeter is 66 cm.
The perimeter is the sum of all the sides of the polygon.
The perimeter is 66 cm, and the sides are in a ratio of 2: 4: 5.
Let’s make the equations.
2 X + 4 X + 5 X = 66.
11 X = 66.
X = 6.
1 side = 2 * 6 = 12 cm.
2 side = 4 “6 = 24 cm.
3rd side = 5 * 6 = 30 cm.
