Problem number 18. Some lawns are shown below. Which lawn is the smallest? A, B, C, D, or E?  So the trick to this problem is to use the dots. We are going to divide the lawns into triangles and count the triangles and all the triangles will be the same size.  And whichever lawn has the least triangles is the smallest. If we look at A, we see there are 1, 2, 3, 4, 5, 6, 7. So A has 7 triangles.  Then we will look at B, which has 1, 2, 3, 4, 5, 6, 7, 8. So B has 8. Then we look at C, and C has 1, 2, 3, 4, 5, 6, 7, 8. So C also has 8.  And if we look at D, we see it has 1, 2, 3, 4, 5, 6, 7, 8. And then if we look at E, we see there are 1, 2, 3, 4, 5, 6, 7, 8. So E has 8.  A has 7 triangles, which means it is the smallest. So our answer is A.

Video Summary

The problem involves identifying the smallest lawn among options A, B, C, D, and E by counting the number of triangles each lawn contains. Each lawn is divided into equally sized triangles. After counting, Lawn A has 7 triangles, while Lawns B, C, D, and E each have 8 triangles. Therefore, Lawn A is the smallest, as it contains the fewest triangles. The answer is A.
