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.
Perimeter of Square = 4 Ã Length. Let's find the area of the rectangle below. To find the area of the rectangle, we find out how many one-centimetre squares we can fit into the rectangle. Area of the rectangle = 4 Ã 2. = 8 cm2. We need 8 one-centimetre squares to make a rectangle 4 cm long and 2 cm wide. The area of the rectangle is 8 cm2.
The perimeter is the distance around the edge of the triangle: just add up the three sides: The area is half of the base times height.  1 b is the distance along the base.  h is the height (measured at right angles to the base)
