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).

multiply each one by 3.14

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
