What is the distance between (4, 6) and (4, -1) ?
7 units
5 units
4 units
I don't know
The distance between points (4,6) and (4,-1) is 7 units.
Given The coordinates of the end points of line (4,6) and (4,-1).
Distance is the measurement about how far things are present on the surface. It is usually calculated in some units known as km, m, etc.
The distance between two points can be calculated as under:
Distance=[tex]\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }[/tex] where the coordinates are (x1,y1),(x2,y2).
To calculate the distance we need to put the values of coordinates in the formula:
Distance between (4,6) and (4,-1)=[tex]\sqrt{(4-4)^{2} +(-1-6)^{2} }[/tex]
=[tex]\sqrt{(0)^{2}+(-7)^{2} }[/tex]
=[tex]\sqrt{0+49}[/tex]
=[tex]\sqrt{49}[/tex]
=7
Hence the distance between (4,6) and (4,-1) is 7 units.

The area of the squared garden is 625 sq. m, what is its perimeter ? (Ans: 100 m)
Answer: Area of square = a*a(where a is length of one side) Putting value a x a=625 cm2 a= 25 Perimeter will be 4 x a 4 x 25 = 100 cm
Step-by-step explanation:
[tex]\sf\huge\underline{Given:-}[/tex]

[tex]\sf\huge\underline{To\: Find:-}[/tex]
[tex]\rightarrow[/tex] Perimeter of the square garden.
[tex]\sf\huge\underline{Formula \:Used:-}[/tex]
Area of square [tex]\sf{= side^2}[/tex]
Perimeter of square [tex]\sf{= 4×side}[/tex]
[tex]\sf\huge\underline{Solution:-}[/tex]
As we know,
[tex]\rightarrow[/tex] Area of square [tex]\sf{= side^2}[/tex](putting the given value of area)
[tex]\rightarrow[/tex] [tex]\sf{Side^2}[/tex] [tex]\sf{= 625}[/tex]
[tex]\rightarrow[/tex] [tex]\sf{Side}[/tex][tex]\sf{= \sqrt{625}}[/tex]
[tex]\rightarrow[/tex][tex]\sf{Side}[/tex][tex]\sf{= 25cm}[/tex]
So, From here we got the side of the square garden that is, 25cm.
Now,

[tex]\rightarrow[/tex] Perimeter of square [tex]\sf{= 4×25}[/tex]
[tex]\rightarrow[/tex]Perimeter of square [tex]\sf{= 100cm}[/tex]
Therefore, perimeter of the square garden = 100cm.
What is the area and perimeter for this
Answer:
Step-by-step explanation:
Side₁ = 1.8 +3.2 = 5 cm
Side₂ = 3 cm
Side₃ = 4 cm
Perimeter of triangle = sum of all the three sides
= 5 + 3 + 4
= 12 cm

One side of a triangle is 5 units longer than a second side. The ray bisecting the angle formed by these sides divides the opposite side into segments that are 7 units and 9 units long. Find the perimeter of the triangle. Give your answer as a reduced fraction or exact decimal
Please explain your answer.
The perimeter of the triangle described in statement has a measure of 56 units long.
How to determine the perimeter of a triangle
After a quick though careful reading, we construct a triangle based on all information given in the statement, based on the fact that the longest segment is adjacent to the longest missing side. Since both sides have two angles with the same magnitude, then we have the following ratios:
[tex]\frac{x}{7} = \frac{x+5}{9}[/tex] (1)
Now we solve the expression for x:
9 · x = 7 · x + 35
2 · x = 35
x = 17.5
And the perimeter of the triangle is determine by summing the three sides:
p = 9 + 7 + (17.5) + (17.5 + 5)
p = 56
The perimeter of the triangle described in statement has a measure of 56 units long. [tex]\blacksquare[/tex]

Answer:
Step-by-step explanation:
First, you would multiply 3x4 =12
next you would keep the denominator the same
last you would divide 8 by 12 10 get 1 3/8 for your answer
The ratio of the measures of the sides of a triangle is 2:11:15. If the perimeter of the triangle is 168 inches, find the length of the longest side.
Answer: 90
Step-by-step explanation:
Let the sides have lengths 2n, 11n, and 15n.
Since the perimeter is 168, 2n+11n+15n=168, meaning that n=6.
So, the longest side is 15(6)=90 inches.
