To find the actual area of the floor in square feet, we need to use the scale factor to convert the dimensions of the scale drawing into actual dimensions.
First, we calculate the scale factor:
Scale factor = actual length / length on drawing = 32 feet / 8 inches = 48
Next, we use the scale factor to find the actual dimensions of the floor:
Actual length = 48 * 8 inches = 384 inches = 32 feet
Actual width = 48 * 5 inches = 240 inches = 20 feet
Now, we calculate the actual area of the floor:
Actual area = Actual length * Actual width = 32 feet * 20 feet = 640 feet^2
Therefore, the actual area of the floor is 640 square feet.
The scale drawing of the rectangular classroom floor has dimensions of 8 inches by 5 inches. The actual length of the longer side of the floor is 32 feet.
