Four ways:1 row with 6 in each row.2 rows with 3 in each row.3 rows with 2 in each row.6 rows with 1 in each row.
8 rows of 6 students 6 rows of 8 students 4 rows of 12 students 3 rows of 16 students 2 rows of 24 students 1 row of 48 students
4/.4 + 4/4 [= 10+1 = 11]
(4+4)+(4/4)+(4/4)
You cannot do that since 5 rows x 4 trees = 20 trees total. But we have 10 trees to plant!
4 Even rows, you'd end up with 2 rows of 3, and another 2 of 2.

Plant them in the shape of a star. The way the five lines (rows) overlap, you only need 10 total.

Draw a five-pointed star. Place five trees on the points and five more where the lines intersect.
Having the same number of students in each row, 80 students can be arranged in 80 rows of 1, 40 rows of 2, 20 rows of 4, 10 rows of 8, and 5 rows of 16.
He planted 10 trees in the shape of a 5 pointed star.If there were 5 trees in a row then 5 x 4 gives you the answer.
Arrange them in the shape of a star with a pentagram at the centre... One tree at each outer point of the star, with another tree at the corner of the pentagram. Each liner of four trees is formed by two points of the star, and two corners of the pentagon.
4 rows of ten is like saying 4x10 so its would be 40
Put a small pentagon inside a larger pentagon...
