Answer:
Perimeter = 30 yd
Area = 43.301 yd²
Step-by-step explanation:
The Triangle has three equal sides of 10 yd each. It is therefore an equilateral triangle with equal angle measuring 60° each.
Thus:
✔️ Perimeter = sum of all sides = 10 + 10 + 10 = 30 yd
✔️Area can be found using, A = ½*ab*Sinθ
Where,
a = 10 yd
b = 10 yd
θ = 60°
A = ½*10*10*Sin 60
A = 43.301 yd² (3 decimal places).
The steps in the patterns A and B form a sequence
The attached diagram represents dots in patterns A and B
<h3>How to draw the diagrams</h3>
For pattern A, we have:
Step 2 = 10 dots
Increment of 3 dots in each step
This means that:
Step 0 = 4 dots
Step 1 = 7 dots
Step 2 = 10 dots
Step 3 = 13 dots
For pattern A, we have the following rule
When n = 0 to 3, we have:
Step 0 = 1 dot
Step 1 = 3 dots
Step 2 = 9 dots
Step 3 = 19 dots
Next, we draw the diagrams of both patterns (see attachment)

Answer:
108 cm³
Step-by-step explanation:
Formula: V = w×h×l
Solution: V = whl = 4·3·9 = 108
Hence, the answer is 108 cm³
N=5 or n=9 can be either one
