List three sets of base and height measurements for triangles with areas of 30 square units?

The area of a triangle is half base times height so any triangles whose base times height is 60 units will have an area of 30 square units e.g.

base = 10 units, height = 6 units;

base = 5 units, height = 12 units;

base = 7.5 units, height = 8 units.
