Side stems affect plant vigor. As a tomato grows, side shoots, or suckers, form in the crotches, or axils, between the leaves and the main stem. If left alone, these suckers will grow just like the main stem, producing flowers and fruit. Suckers appear sequentially, from the bottom of the plant up.
The perimeter of a two-dimensional shape is the total distance around the shape, or the sum of the length of its sides. By definition, a square is a four-sided shape with four straight sides of equal length, and four right (90Â°) angles.
Perimeter of a rectangle. The total distance around the outside of a rectangle is called perimeter of rectangle. The perimeter is the total distance around the outside, which can be found by adding together the length of each side. In the case of a rectangle, opposite sides are equal in length, so the perimeter is twice its width plus twice its height.
