Show your work for this problem. Be sure to show each step and explain using math vocabulary. And write it like a 7 grader
First, we need to find the scale factor used in the scale drawing.
Scale factor = Actual length / Length in drawing
Scale factor = 32 feet / 8 inches = 4
Now, we can find the actual width of the classroom floor using the scale factor.
Actual width = 4 * 5 inches = 20 feet
The actual area of the classroom floor is:
Actual area = Actual length * Actual width
Actual area = 32 feet * 20 feet
Actual area = 640 square feet
Therefore, the actual area of the floor is 640 square feet, so the answer is C. 640 feet2.
