The length of the rectangular piece of land was increased by 7 m and the width by 4 m.

The length of the rectangular piece of land was increased by 7 m and the width by 4 m. How many square meters has the area increased if the original dimensions of the site are 50m by 36m.

1) Find the area of ​​the original size of the site. The area of ​​a rectangle is equal to the product of length and width: S = a * b. Substituting our values ​​for length 50 m and width 36 m, we get: S = 50 m * 36 m = 1800 square meters.

2) Since the length of the rectangular piece of land was increased by 7 m, the value of the length became: 50 m + 7 m = 57 m.
3) Since the width of the rectangular piece of land was increased by 4 m, the value of the width became: 36 m + 4 m = 40 m.

4) Find the area of ​​a rectangle with sides 57 m long and 40 m wide: S = 57 m * 40 m = 2280 square meters.

5) Find out how many square meters the area has increased: 2280 square meters – 1800 square meters = 480 square meters. Answer: 480 sq. M.
