11. Weight Loss The scatter plot below shows the weight loss per week of a dieter. In the graph, y represents the person's weight in pounds and x represents the weeks of the diet. Find an equation of the line that you think best fits this data. Then use the equation to find the dieter's approximate weight after 10 weeks.

The base of the pyramid is the triangle on the very bottom. The formula for the area of a triangle is A = 1/2 x base x height.

In this triangle, the base length is 6 cm and the height is 7 cm, as shown clearly in the image. Using the formula for the area, we can easily solve for the area of this triangle.

A = 1/2 x 6 x 7

A = 1/2 x 42

A = 21 cm^2

Hope this helps! :)
