Given a ratio of sides and perimeter find the lengths of a triangle

The video tutorial explains how to determine the perimeter of a triangle by adding its sides. It introduces the concept of ratios and equivalent ratios, demonstrating how to find a scalar factor to solve for unknowns. The tutorial concludes with calculating the side lengths of a triangle using the scalar factor.

Explain how multiplying the sides of a triangle by a scalar factor affects the perimeter.

What steps would you take to find the missing side lengths of a triangle if you know the perimeter and the ratios?
