Area of square= s^2
12.25=s^2
take the sqrt(12.25) = 3.5
Perimeter of square = 4s
P=4(3.5)
P= 14 m
The answer is B. 18
Explanation:
We know that a square has 4 right angles. A right angle is 90°.
5x° = 90°
5(18)° =90°
90°=90°
Hope this helps some
Given : - Square ABCD with side 3. E and F as midpoints.
To find : - area of EBFD
Solution : - We have, area of square ABCD = 3 x 3 = 9 units.
Thus, (ar)EBFD = ar ABCD - ar DAE - arDCF
arDAE = 1/2 x base x height
=1/2 x 1.5 x 3 ( AE is 1/2 of AB = 1.5, DA is altitude)
= 2.25
arDFC = 1/2 x base x height
= 1/2 x 1.5 x 3 (FC is 1/2 of BC, DC is altitude)
= 2.25
Thus, (ar) EBFD = arABCD - arDAE - arDCF
= 9 - 2.25 - 2.25
= 4.5 units.
Thus, area of quad EBFD is 4.5 units.
Basically, it is not a function because 1 domain (in this case, 5) can not be connected to two different ranges(1 and -2). Each domain must only connect to one range.
We know that
1 mile----------------> 1609.34 meters
26 miles---------------> X
X=26*1609.34=41842.84 m
I apply a rule of three to know the time
if 100 m---------------9.96 sec
41842.84 m----------> x
x=41842.84*9.96/100=4167.5468 sec
to get minutes I divide it by 60---------> 4167.5468/60=69.459113 minutes
to get hours I divide it by 60----------> 69.459113/60=1.1576518 hours
1.1576518= 1 hour 9 minutes 27.55 sec
the answer is 1 hour 9 minutes 27.55 sec------->(4167.5468 sec)
