Question 1 (3 points) 1. Use the moving and additivety principles to determine the area (in square units) of the triangle in two different ways. Do not use a formula for areas of triangles. The grid lines are 1 unit apart. Explain your reasoning.Question 2 (3 points) 2. For each triangle, show the height of the triangle that corresponds to the indicated base b. Then use these bases and heights to determine the area of each triangle. Question 3 (3 points) 4. Explain clearly in your own words why the triangles in the figure have area 1 5(1) - h) for the given choice of base b and height h. 1 cm D B C AQuestion 4 (3 points) 7. Explain how to use the additivety principle to determine the area of the darkly shaded triangle that is inside a rectangle in the figure. 5 units 2 units- 2 units 2 unitsQuestion 7 (3 points) 10. Determine the area of the shaded triangle in the figure in two different ways. Explain your reasoning in each case
