13.5•18 = 243 inches squared
Arcsin is the inverse function of sine, it switches the sine function (reverses it)
cosec is the reciprocal of sine
Answer:
P = perimeter
A = area
l = lenght
w = width
P = 2 x l + 2 x w
A = l x w
18 ft = 2 x l + 2 x w
18 ft² = l x w
Input l = 6 ft w = 3 ft
18 ft = 12 ft + 6 ft = 18 ft
18 ft² = 6 ft x 3 ft = 18 ft²
Answer:
l = 6 ft
w = 3 ft
