A rectangular plot of land is sown with grass, the size of the plot is 22 x 28m, how many kilogram packages of seeds are required if the contents of one package are enough to sow 70m2.

a = 22 m;
b = 28 m;
S =? m².

The area of a rectangle is equal to the product of the width of the rectangle by its length (height) or equal to the product of its sides and is calculated by the formula: S = a * b.
1) S = 22 * 28 = 616 (m²).

2) 616: 70 = 8.8 (package)

3) 8.8 is rounded, since 8.8 is more than 8.5, we get 9.
