The apothem is the distance from which the altitudes of the triangle to one of its sides. It can be calculated through the equation below,
                             tan 30° = apothem / 0.5(length of side)
Substituting the known values,
                             tan 30° = 5 / 0.5x
The value of x from the equation above is 17.32. Multiplying this value by 3 (because a triangle has 3 sides), we get an answer of 51.96 cm or approximately equal to 52. Thus, the answer is letter B. 
        
             
        
        
        
Answer:
Below.
Step-by-step explanation:
When you graph this you'll see that it is a rhombus, which has 4 equal sides and the 4 angles are not 90 degrees.
You could draw a square on the coordinate plane using A(0.0). B (0,3), C(3,3) and D(3,0). The sides of the square are all equal to the sides of the rhombus but the 2 quadrilaterals are not congruent because the angles have different values,
 
        
                    
             
        
        
        
Answer:
assume it's width as 'x'
So, it's length is '2x-3'
and the perimeter is equal to 66m
Step-by-step explanation:
So,equalize the equation
x + (2x-3) + x + (2x-3) = 66
remove the brackets 
2x + 4x - 6 = 66
add 6 to both sides
6x = 60
x = 60 ÷ 6
 = 10
so, the length is 2x-3 = 20 - 3 = 17 m
 and the breadth is x = 10 m
