The length of the rectangular piece of land was increased by 7 m, and the width by 4 m. How many square meters did the area increase if the original dimensions of the plot were 50m * 36m?

1) Let us calculate the area of a plot of land with the original dimensions by the formula: S = a • b = 36 • 50 = 1800 (m²);
2) Find the new value for the width of the plot of land: 36 + 4 = 40 (m);
3) Determine what the new value of the length of the land is equal to: 50 + 7 = 57 (m);
4) Let’s calculate the new value of the area of the land plot: S = a • b = 40 • 57 = 2280 (m²);
5) Find out by how many m² the area of the land plot increased with the increase in its length and width: 2280 – 1800 = 480 (m²).
Answer: the area of a plot of land has increased by 480 m² with an increase in its length and width.
