When two quantities x and y are directly proportional , then the equation that shows direct variation is given by :-

Given : The shadow cast by an object on a sunny day is directly proportional to the height of the object.

Let x be the height of tree.

According to the the given question , we have

Hence, the height of tree = 47.36 feet.
