Understanding the Area of a Triangle and Solving for the Base

The video tutorial explains how to solve for the base of a triangle using the area formula. It outlines the steps to isolate the base variable, including underlining the variable, using the reverse order of operations, and employing reciprocals to simplify the equation. The tutorial concludes with the final solution for the base in terms of the area and height.

What is the formula for the area of a triangle?

• 1/2 * base + height

• base + height

• base * height

• 1/2 * base * height

What happens when you multiply both sides of an equation by the reciprocal of a fraction?

• The fraction cancels out

• The fraction doubles

• The fraction is added to both sides

• The fraction is subtracted from both sides
