Answer:
2 Movements
Step-by-step explanation:
Let us name the tokens
B-For Black Tokens
W-For White Tokens
The initial arrangement is therefore given as:
B-B-B-B-W-W-W-W-W
Since we are allowed to flip three tiles in each turn
First movement: Flip two blacks and one white, we would have:
B-B-W-W-W-W-W-W-B
Second movement: Flip the three black tokens, this would give us:
W-W-W-W-W-W-W-W-W
Therefore, the least number of movements to have all tokens showing the same color is 2.
The perimeter of the rectangle is 21.6 m
To solve the above questions, we need to recall some of the formulas as follows:
Area of Square = (Length of Side)²
Perimeter of Square = 4 × (Length of Side)
Area of Rectangle = Length × Width
Perimeter of Rectangle = 2 × ( Length + Width )
Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )
Perimeter of Rhombus = 4 × ( Length of Side )
Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )
Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )
Let us now tackle the problem !
Given:
Length of Diagonal = d = 8 m
Angle Between Diagonal and Width = θ = 60°
Unknown:
Perimeter = ?

Since the triangle is right angled, we may use pythagoras theorem to find the third side.
Pythagoras theorem :-
KI^2 + JI^2 = KJ^2
substituting the known values in the formula,
x^2 + 3^2 = 5^2
x^2 + 9 = 25
x^2 = 25 - 9
x^2 = 16
x = √16
x = 4

Hello!
If x² equals 1/100, then x equals 1/10 or -1/10.
I hope it helps!
