Answer: The length is 13 inches and the width is 11 inches.
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The formula for determining the area of a rectangle is expressed as
Area = LW
The area of the rectangle is 143 square inches. This means that
LW = 143 - - - - - - - - - - - - --1
The rectangle's length is 2 in more than its width. This means that
L = W + 2
Substituting L = W + 2 into equation 1, it becomes
W(W + 2) = 143
W² + 2W - 143 = 0
W² + 13W - 11W - 143 = 0
W(W + 13) - 11(W + 13) = 0
W + 13 = 0 or W - 11 = 0
W = - 13 or W = 11
Since the width cannot be negative, it means that W = 11
L = W + 2 = 11 + 2
L = 13
You got the b part wrong. It would be 4B+4C/2=4D

Answer:
The value of π = 22/7 = 3.14
So here the Equation given we can examine those
1. 3π -1 > 9
=> (3 * 3.14 ) -1 > 9
=> 9.42 – 1 > 9
=> 8.42 > 9 , which is false
2. 7π > 21
=> (7 * 3.14) > 21
=> 21.98 > 21 , Which is true
3. π + 4 < 7
=> 3.14 + 4 <7
=> 7.14 <7 , Which is false
4. (12/ 4π) > 1
=> {12/ (4 * 3.14)} > 1
=> (12/12.56) > 1
=> 0.955 > 1 , Which is false
