First, let's look at the formulas for the area of square and area of the rectangle.
And what this exercise states is that the areas are the same. So:
Now put in the data.
Solve for 
:
The side of the square garden plot is 4 meters.
Hope this helps.
r3t40
the starting amount would be the 550, because it doesn't have a variable assigned to it.

Answer:
Radius
Step-by-step explanation:
A circle is made of specific components which define its shape. It has a fixed center which is equidistant apart from all points at its edge. The distance from the center to each point is called its radius. The distance from its edge through its center to the opposite edge is called the diameter.
Answer:
Optical axis
Step-by-step explanation:
Optical axis is the rotational symmetry axis of the surfaces.
A line with a certain degree of rotational symmetry is called as the optical axis in an optical system.
It is the straight line that passes through the geometric center of the lens and joins two curvature centers of its surfaces.
It is also called as the principal axis.
