Answer:
66
Step-by-step explanation:
Answer:
We will take option B.
Step-by-step explanation:
Option A) |4 − 1| = 3 units
Option B) |4 − (−1)| = 5 units
Option C) |−4 + (−1)| = 5 units
Option D) |−4 − (−1)| = 3 units.
Now, from the number line and from the points given on the number line it is clear that the distance from one point to another is 5 units.
So. option B or Option C can be the right one.
Now, the right side point is on +4 point and the left side point is on -1 point.
So, the distance between those points will be calculated as 4 - (- 1) = 5.
Therefore, we will take option B. (Answer)

The total length of a boundary defines the perimeter of an equilateral triangle.
<h3>What is the Perimeter of an Equilateral Triangle?</h3>
- The total of the three sides makes up the perimeter of an equilateral triangle.
- The following fundamental characteristics define a triangle as being equilateral:
- The three sides are equal.
- There is a 60° angle between all three.
- The sides of the triangle PQ = QR = RP in the following illustration have equal lengths.
- The triangle's angles are also equal in addition to this. An equilateral triangle is what this is.
- An equilateral triangle's perimeter is now equal to 3a, where a denotes one of the triangle's sides.
- Perimeter of Equilateral Triangle Formula : P = 3a, where 'a' stands for one of the triangle's sides, is a simple formula for calculating an equilateral triangle's perimeter. An equilateral triangle has three equal sides, hence the sum is equal to three equal sides, or 3a.
- Additional equilateral triangle formulas include the following: When we need to determine a triangle's height from its sides, we can apply the following formula: Equilateral Triangle Height = (3a)/2
- The semi-perimeter of an equilateral triangle must be determined in a few situations. Half of a perimeter, or semi-perimeter, is equal to 3a/2, which is derived using the formula semi-perimeter = (a + a + a)/2.
