Question

The perimeter of an equilateral triangle is $145\text{feet}$. Find the length of each side?

Answer 1

Length of sides of equilateral triangle:

The perimeter of the equilateral triangle is $145\text{feet}$.

That implies, the sum of sides of the triangle is $145\text{feet}$.

But in case of equilateral triangle the length of each sides are equal.

Thus, the length of each sides is $\frac{145}{3}\text{feet}$.

Hence, the length of each side is $48.33\text{feet}$.
