Finding the Sides of an Equilateral Triangle

To find the sides of an equilateral triangle, we need to consider the given information: the perimeter of the triangle is 85 cm, and the base is 2 times smaller than the other two sides.

Let's assume that the length of the base is x cm. Since the base is 2 times smaller than the other two sides, each of the other two sides will have a length of 2x cm.

The perimeter of an equilateral triangle is the sum of all three sides. In this case, it is given as 85 cm. Therefore, we can write the equation:

x + 2x + 2x = 85

Simplifying the equation, we get:

5x = 85

Dividing both sides of the equation by 5, we find:

x = 17

Now that we have found the value of x, we can substitute it back into the equation to find the lengths of the sides:

Base: x = 17 cm

Other two sides: 2x = 2 * 17 = 34 cm

Therefore, the sides of the equilateral triangle are:

Base: 17 cm

Other two sides: 34 cm

Please note that the lengths of the sides are in centimeters (cm).
