In 200, Jim planted a tree that was 4 1/2 feet tall. In 2005, the tree was 15 3/4 feet tall. Assuming the growth of the tree is linear, what was the rate of growth of the tree?

I’m still confused on how to work the percentages

What is the answer to this equation?

Which equation can be used to calculate the area of the shaded triangle in the figure below? (5 points) 2(12 × 4) = 96 square feet (12 × 4) = 24 square feet 2(12 + 4) = 32 square feet (4 + 12) = 8 square feet
