Final answer:
4.5 sections consist of 2880 acres, which is calculated by multiplying the number of sections (4.5) by the acres per section (640).
Step-by-step explanation:
To calculate how many acres are in 4.5 sections, we need to understand the measurements of the land. In the grid system, a township is divided into 36 sections. Each section is a square-mile parcel of land. Since one square mile equals 640 acres, each section contains 640 acres.
To find out how many acres are in 4.5 sections, we simply multiply the number of sections by the number of acres in one section:
4.5 sections × 640 acres/section = 2880 acres.
Therefore, 4.5 sections consist of 2880 acres.
