Answer: The length of one side of the actual building is 921 feet
Step-by-step explanation:
If the scale of the actual building to the drawing is 307 feet to 5 inches, it means that 1 feet on the building would be
5/307 inches
The scale drawing of the building in the shape of a pentagon has a perimeter of 75 inches. A Pentagon has 5 sides. It means that the length of each side of the building on the drawing is
75/5 = 15 inches
Since 1 feet on the building = 5/307 inches on the drawing, then
x feet on the building = 15 inches on the drawing.
x = (15 × 307)/5 = 921 feet
Answer:
921 feet
Step-by-step explanation:
If each side of the building measures the same length, and the perimeter is 75 inches, we have that each side in the scale drawing is 75/5 = 15 inches.
Now, to find the actual length of the building side, we can use a rule of three:
307 feet of actual side is 5 inches in the scale, so what's the length of the actual side for a 15 inches side in the scale:
307 feet -> 5 inches
x feet -> 15 inches
307/x = 5/15
5x = 307*15
x = 307*15/5 = 921 feet
