Question

a trapezoid was broken into a rectangle and a triangle.
what is the length, b, of the base of the triangle?

Explanation:

Step1: Analyze the relationship between trapezoid and its parts

The upper base of the trapezoid is \(8\) cm, and the lower base is \(10\) cm. When the trapezoid is divided into a rectangle and a triangle, the length of the rectangle's side is equal to the upper base of the trapezoid.

Step2: Calculate the base of the triangle

The base \(b\) of the triangle is the difference between the lower base and the upper base of the trapezoid. So \(b = 10 - 8\).

Answer:

\(2\) cm
