Answer:
If demand for land increases, the rental price RAISES / INCREASES and the equilibrium amount of land REMAINS THE SAME.
Step-by-step explanation:
The supply of some products is fixed in the short run and one example of this is land either for urban development or agriculture. It is possible but extremely expensive to "create" land, so the supply is usually considered constant. On the long run, humanity has managed to artificially create islands and expand cities, but these type of projects require a lot of money and take a lot of time.
The short run or the long run are not definite time spans. The short run refers to a period of time where one or more factors of production are fixed. While the long refers to a time period where all factors of production can change.
