Finding the Average Side of a Similar Triangle

To find the average side of a similar triangle, we need to use the concept of proportionality. Given that the sides of the original triangle are proportional to the numbers 2, 5, and 4, and the smaller side of the similar triangle is 50 cm, we can set up the following proportion:

Original Triangle: Side 1: 2 Side 2: 5 Side 3: 4

Similar Triangle: Side 1: 50 cm Side 2: ? Side 3: ?

Using the concept of proportionality, we can set up the following equation:

Side 1 of Original Triangle / Side 1 of Similar Triangle = Side 2 of Original Triangle / Side 2 of Similar Triangle

Substituting the given values:

2 / 50 = 5 / Side 2 of Similar Triangle

To find the value of Side 2 of the similar triangle, we can cross-multiply and solve for it:

2 * Side 2 of Similar Triangle = 50 * 5

Side 2 of Similar Triangle = (50 * 5) / 2

Simplifying the equation:

Side 2 of Similar Triangle = 250 / 2

Side 2 of Similar Triangle = 125 cm

Therefore, the average side of the similar triangle, where the smaller side is 50 cm, is 125 cm.
