How do you calculate perimeter, area and volume using scales?
The calculate the perimeter of the land when given an aerial photograph, multiply the length on the aerial photo by the scale. To calculate the area, find the measurements, multiply by the scale, and ensure you use the appropriate formula (e.g. area of a triangle formula). To calculate volume, you will need to use the trapezoidal rule, which will be covered in detail below. This post will show you how to calculate perimeter, area and volume in the HSC Standard Math Course.
