Problem
QUESTION 1 Use a proportion to solve the problem. A tree casts a shadow \( 42 \mathrm{~cm} \) long. At the same time, the shadow cast by a 49-cm tall statue is \( 63 \mathrm{~cm} \) long. Find the height of the tree. Round your answer to the nearest tenth of a meter. \( 52.5 \mathrm{~cm} \) \( 31.2 \mathrm{~cm} \) \( 54.0 \mathrm{~cm} \) \( 32.7 \mathrm{~cm} \)
Solution
Step 1 ：\(\frac{tree}{42} = \frac{49}{63}\)
Step 2 ：\(tree = 42\cdot\frac{49}{63}\)
Step 3 ：\(tree = 32.6667\)
