Curated and Reviewed by Lesson Planet

This Painted Stage assessment also includes:

Find the area as it slides. Pupils derive an equation to find the painted area of a section of a trapezoidal-shaped stage The section depends upon the sliding distance the edge of the painted section is from a vertex of the trapezoid. Scholars use their equations to create graphs of the areas in terms of distance.
