Answer:
The height of the birdhouse is 20ft
Step-by-step explanation:
Length of bird house shadow = 14 feet
Length of your friend shadow = 3.5 feet
Height of your friend = 5 feet
Height of the birdhouse = ?
To find the height of the birdhouse we will compare the quality of the two parameters.
Height of your friend / Length of your friend shadow = Height of the birdhouse / Height of the birdhouse
Therefore we have:
5ft/3.5ft = x/14ft
Cross multiple
3.5x = 70
x = 70/3.5
x = 20ft.
Therefore, the height of the birdhouse is 20ft
