Step-by-step explanation:
x(x-4) = 192
the Equation:
x²-4x -192 =0
=> (x-16) (x+12) =0
x= 16 or x= -12
since the x should be a possitive, so x = 16
the dimension :
the length = 16 m
the width = 12 m
Answer:
Step-by-step explanation:

Question #32:</h3>
Solve: 4/m - 8 = 8/2
Cross Multiply: 4 * 2 = 8 * (m - 8)
Simplify: 8 = 8m - 64
Flip the Equation: 8m - 64 = 8
Add 64 to both sides: 8m + (-64) + 64 = 8 + 64
Simplify: 8m = 72
Divide both sides by 8: 8m/8 = 72/8
Final Answer: m = 9

<h3>
Question #33:</h3>
Solve: 7/b + 5 = 10/5
Cross Multiply: 7 * 5 = 10 * (b + 5)
Simplify: 35 = 10b + 50
Flip the Equation: 10b + 50 = 35
Subtract 50 to both sides: 10b + 50 - 50 = 35 - 50
Simplify: 10b = -15
Divide both sides by 10: 10b/10 = -15/10
Final Answer: b = -3/2
