Problem 4
Lin and Andre used different methods to find the area of a regular hexagon with 6-inch sides. Lin decomposed the hexagon into six identical triangles. Andre decomposed the hexagon into a rectangle and two triangles.
Find the area of the hexagon using each person’s method. Show your reasoning.
Problem 5 From Unit 1 Lesson 9
Identify a base and a corresponding height that can be used to find the area of this triangle. Label the base
and the corresponding height . Find the area of the triangle. Show your reasoning.
Problem 6 From Unit 1 Lesson 10
On the grid, draw three different triangles with an area of 8 square units. Label the base and height of each triangle.
