Answer:
Perimeter of rectangle ABCD = 32.8 unit (Approx.)
Step-by-step explanation:
Given:
Hypotenuse BD = 12 unit
Angle θ = 30°
Find:
Perimeter of rectangle ABCD
Computation:
Using trigonometry function
Sin θ = Perpendicular / Hypotenuse
Sin 30 = CD / BD
0.5 = CD / 12
Length of CD = 6 unit
Cos θ = Base / Hypotenuse
Sin 30 = BC / BD
0.866 = BC / 12
Length of BC = 10.4 unit
Perimeter of rectangle ABCD = 2[Length + Width]
Perimeter of rectangle ABCD = 2[6 + 10.4]
Perimeter of rectangle ABCD = 2[16.4]
Perimeter of rectangle ABCD = 32.8 unit (Approx.)
Before you do anything, you convert 1/4 into 0.25. Then you start multiplying. If you don't understand email me at

Following are the answer to this question:
Step-by-step explanation:
Given value:
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, ...
Multiples of 6: 6, 12, 18, 24, 36, 42, 48, 54, 60, 66, ...
Multiples of 11: 11, 22, 33, 44, 55, 66, ...
The lcm of 2, 6, and 11 is 66
I believe all you do is add the numbers with the same coefficients so 2x + 5x + x (in front of x is understood to be a 1) So you get 8x. And 8 + 1 is 9 so the perimeter is B. 8x + 9
