Answer: The real tree house door should be 126 cm tall.
Explanation:
Given: Two students make a model of a tree house they want to build. The scale is 1:42.
i.e. 1 cm of model = 42 cm in real
if the in the scale model,the door is 3 cm tall, then the height of real tree house door = 3 x (42) cm
⇒ Height of real tree house door= 126 cm
Hence, the real tree house door should be 126 cm tall.
The length is 88 cm, multiply the width by two and subtract it from the whole perimeter. Then divide the whole perimeter again by two to find the length of one side.
