<h2>Given :- </h2><h2 />
- Side of the square field = 70m
- Length of the rectangular field = 90m
- Breadth of the rectangular field = 60m
<h2>To Find :-</h2>
- Perimeter of the square field
- Perimeter of the rectangular field
<h2>Solution :-</h2>
Perimeter of the square = 4 × side
By substituting values,
⇒ 4 × 70m
➥ 280m
<h3><u>Hence, </u><u>Faliha</u><u> runs 280m around a Square </u><u>field</u></h3>
Perimeter of the rectangle = 2( length + Breadth)
By substituting values,
⇒ 2( 90m + 60m )
⇒ 2( 150m)
➥ 300m
<h3><u>Hence, Rameen runs 300m around a rectangular field</u></h3>
By comparing perimeters, Rameen runs more than Faliha
Distance runs more by rameen = Distance covered by rameen - distance covered by faliha
By substituting values,
⇒ 300m - 280m
➠ 20m
<h3><u>Hence, </u><u>Rameen</u><u> runs more around a rectangular field by 20</u><u>m</u></h3>

Answer:
the mean and standard deviation is 2300 and 100 respectively
Step-by-step explanation:
Given that
Mean = 2300
Standard deviation = 500
let us assume the x be the mean of living space
And, the sample is of 25 homes
We need to find out the mean and the standard deviation
So here mean = 2300
And, the standard deviation
= 500 ÷√25
= 500 ÷ 5
= 100
hence, the mean and standard deviation is 2300 and 100 respectively
Assume P(xp,yp), A(xa,ya), etc.
We know that rotation rule of 90<span>° clockwise about the origin is
R_-90(x,y) -> (y,-x)
For example, rotating A about the origin 90</span><span>° clockwise is
(xa,ya) -> (ya, -xa)
or for a point at H(5,2), after rotation, H'(2,-5), etc.
To rotate about P, we need to translate the point to the origin, rotate, then translate back. The rule for translation is
T_(dx,dy) (x,y) -> (x+dx, y+dy)
So with the translation set at the coordinates of P, and combining the rotation with the translations, the complete rule is:
T_(xp,yp) R_(-90) T_(-xp,-yp) (x,y)
-> </span>T_(xp,yp) R_(-90) (x-xp, y-yp)
-> T_(xp,yp) (y-yp, -(x-xp))
-> (y-yp+xp, -x+xp+yp)
Example: rotate point A(7,3) about point P(4,2)
=> x=7, y=3, xp=4, yp=2
=> A'(3-2+4, -7+4+2) => A'(5,-1)
Answer:
the answer to this question is 121 but there is a problem with that question because its common difference is not the same
Answer:
55
Step-by-step explanation:
You can do:
81 - 26 = 55
The sum of the angles (81) minus the angle that is represented (21)
