The length of the rectangular section is 120 m, the width is 75% of the length.

The length of the rectangular section is 120 m, the width is 75% of the length. 35% of the plot was plowed. How much land area is left to plow?

1) Determine what the width of this piece of land is equal to: 120: 100 · 75 = 90 (m);

2) Calculate the area of the site using the formula: S = a · b = 120 · 90 = 10800 (m²);

3) Find out what the area of the part of the plot that was plowed is equal to: 10800: 100 · 35 = 3780 (m²);

4) Find the area of the plot left to plow: 10800 – 3780 = 7020 (m²).

Answer: 7020 m² of land remains to be plowed.
