Find the area of the rectangle. You can find the area of a rectangle with the following formula:
![A = wl](https://tex.z-dn.net/?f=A%20%3D%20wl)
w = width, and l = length.
Plug in your width and length:
![20 * 10 = 200](https://tex.z-dn.net/?f=20%20%2A%2010%20%3D%20200)
The area of the rectangle is 200 square centimeters.
The area of a square is also given by width * length. Multiply the sides together:
![2x * 2x = 4x^{2}](https://tex.z-dn.net/?f=2x%20%2A%202x%20%3D%204x%5E%7B2%7D)
The area of a square is 4x^2.
Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:

Answer:
3.) 0.894
Step-by-step explanation:
✔️First, find BD using Pythagorean Theorem:
BD² = BC² - DC²
BC = 17.89
DC = 16
Plug in the values
BD² = 17.89² - 16²
BD² = 64.0521
BD = √64.0521
BD = 8.0 (nearest tenth)
✔️Next, find AD using the right triangle altitude theorem:
BD = √(AD*DC)
Plug in the values into the equation
8 = √(AD*16)
Square both sides
8² = AD*16
64 = AD*16
Divide both sides by 16
4 = AD
AD = 4
✔️Find AB using Pythagorean Theorem:
AB = √(BD² + AD²)
AB = √(8² + 4²)
AB = √(64 + 16)
AB = √(80)
AB = 8.9 (nearest tenth)
✔️Find sin x using trigonometric ratio formula:
Reference angle = x
Opposite side = BD = 8
Hypotenuse = AB = 8.944
Thus:
(nearest thousandth)
