The rectangular plot of land is shown on the plan at a scale of 1: 300.

The rectangular plot of land is shown on the plan at a scale of 1: 300. What is the area of the land plot if the area of its image on the plan is 18 cm2.

Since the scale of both the length and width of this section is 1300, and the area is the product of the width and the length, then we need to multiply the known value twice by 300 and translate it into more convenient values, for example, in meters:
18 * 300 * 300 = 1 620 000 cm. Sq.
1 sq. M. = 10,000 cm. Sq.
1,620,000 / 10,000 = 162 sq.
Answer: 162 sq.
