11-61.

While trying to measure the height of a tree, Julie notices that a $3.5$-foot post has a $4.25$-foot shadow. If the tree’s shadow is $100$ feet long, how tall is the tree?

Draw and label a picture.

The ratio between the height of the object and the length of the shadow will be the same for both the tree and the post.
