Answer:  18</h3>
==========================================================
Explanation:
2 cm on paper (or on screen) represents 3 meters in real life. 
The backyard is 2 cm horizontally across on the screen, so it's 3 meters across in real life. This is the shorter dimension. 
The longer dimension is 6 meters. We can think of it like this
2 cm : 3 meters
2*2 cm : 2*3 meters .... multiply both sides by 2
4 cm : 6 meters
The real backyard is 6 meters by 3 meters to give an area of 6*3 = 18 square meters.
 
        
             
        
        
        
For a regular tessellation, the shapes can be duplicated infinitely to fill a plane such that there is no gap. The only shapes that can form regular tessellations are equilateral traingle(all sides are equal. This means that it can be turned to any side and it would remain the same), square and regular hexagon. Looking at the given options, we have
Shape Tessellate?
Octagon No
Hexagon Yes
Pentagon No
Square Yes
Triangle No(unless it is specified that it is an equilateral triangle)
 
        
             
        
        
        
V = (1/3)pi*r^2*h that's the formula to used to get the volume of the cone
