Olivia goes to Egypt and sees a model of a pyramid. She enlarges it using a scale factor of 1.2. What will be the perimeter and area of the new triangular pyramid?
Answer (2)
The perimeter will be the perimeter of the real thing divided by 1.2 .
The area will be the area of the real thing divided by (1.2)² .
When Olivia enlarges the pyramid model by a scale factor of 1.2, the new perimeter becomes 1.2 times the original perimeter, while the new area becomes 1.44 times the original area. Thus, to find the new measurements, simply multiply the original values by the appropriate factors. This method illustrates how scaling affects both perimeter and area in geometry.
