The area of the model is 80 square foot
Step-by-step explanation:
Let the area of the house model be 'a'
The scale = 1:50
The area of the house= 4000 square foot
Area of the model =4000/50
a = 80 square foot
The area of the model is 80 square foot
Move the decimal point one to the right on both sides so it would be 70/203. After that you can divide it by adding more 0s to 70. Like, 70.00 until you get an answer
