yes
Yes, the measure of the number of unit squares needed to cover a surface is referred to as the area of that surface. Area quantifies the extent of a two-dimensional shape and is typically measured in square units, such as square meters or square feet. Thus, counting the unit squares provides a practical way to determine and visualize the total area.
Area is a measure of square units.
Surface area of shapes can be measured in square centimetres
It is the surface area of the solid.
Square yards would be a surface area measurement (3ft x 3ft), to measure surface area of a flat surface measure the length and width (in yards) then simply the two together .for example 5yards x 2 yards = 10 square yards=10 yards2To measure the surface area of a nonuniform surface you would need very specific tools and programs, that are not easily available.Measuring the square yards of sand is very unusual and what you may mean is "how do I measure cubic yards of sand?"

square units
Probably a wall of some sort.
square inches
anything as long as its on the surface area
That's a 'hectare'.
You can put an infinite number of square units on any surface if the unit is infinitely small
