What is the length of BD?
In the given figure, the length of BD is 14. The correct option is A.
What is the length?Length is the measurement of the extent of something from one end to another, end. The SI unit of length is a meter (m).
Given, that AB is twice the length of BC
BC = CD
DE is a triple of CD
The length of AE is 19
Let's assume BC and CD = x
We have to calculate the length of the CD.
AB = 2x
DE = 3x
Putting the values:
2x + 3x = 49
7x = 49
x = 49 / 7
x = 7
BC and CD = x
7x + 7x = 14x
Therefore, the correct option is A. 14 regarding the given line.

Answer: A
Explanation: Took a test with the same question and got it correct
What is the positive difference between the circumference of circle B and the circumference of circle A?
The positive difference between the circumference of circle B and the circumference of circle A is 1. Thus, the correct option for this question is A.
What is the circumference of the circle?The circumference of the circle may be defined as the total stretch of the boundary of the circle. The formula for calculating the circumference of the circle is as follows:
C = 2πr.where, C = circumference of the circle.
π = the constant pie.
r = radius of the circle.
According to the question,
The circumference of the circle A = 2π (r+1).
The circumference of the circle B = 2π (r+2).
∴The positive difference between the circumference of circle B and the circumference of circle A is as follows:
2π (r+2) - 2π (r+1) = 1.
Therefore, the positive difference between the circumference of circle B and the circumference of circle A is 1. Thus, the correct option for this question is A.
