Answer: 140cm²
Step-by-step explanation:
Perimeter of a rectangle is calculated as: = 2(length + width)
where,
Length = x+4
Width = x
Therefore, perimeter = 2(length + width)
2(x + x+4) = 48
2(2x + 4) = 48
4x + 8 = 48
4x = 48 - 8.
4x = 40
x = 40/4
x = 10cm
The other side = x+4 = 10+4 = 14cm
Area = length × width
Area = 10cm × 14cm
Area = 140cm²

Answer:
4%
Step-by-step explanation:
The probability that two smoke is the product of the probabilities that each smokes, provided the students are selected independently.
... 0.20 × 0.20 = 0.0400 = 4%
If you would like to know the volume of the box, you can calculate this using the following steps:
1 foot = 12 inches
1.5 feet = 18 inches
volume = length * width * height = 14 inches * 1.5 feet * 7 inches = 14 * 18 * 7 = 1764 inches^3
The volume of the box is <span>1764 inches^3.</span>
