Answer:
perimeter = sum of all sides. this is same for polygons
rect: area l×b. peri = 2(l+b)
Step-by-step explanation:
15+5 = 20
20*2 = 40 cm is the perimeter of the given figure
Answer: 13.722 km ; or, write as: 13 13/18 km .
___________________________________________________
Explanation:
___________________________________________________
Area = Length * width ;
___________________________________________________
or, write as: A = L * w ;
________________________
Given: A = 247 km² ;
L = 18 km ;
w = "y" ;
________________________
Find: "y"
______________________________
A = L * w ;
______________________________
Plug in our values:
______________________________
247 km² = 18 km * "y" ; solve for "y" (in units of "km") ;
_____________________________
18 y = 247 ;
___________________________________________________________
Divide each side of the equation by "18"; to isolate "y" on one side of the equation; and to solve for "y" :
___________________________________________________________
18 y / 18 = 247 / 18 ;
_____________________________________________
to get:
_____________________________________________
y = 13.7222222222222222...... km ; round to: 13.722 km
or; y = 13 13/18 km .

So, we need to figure out how much times the body size of the flea it can jump. First, we need to figure out the size of the flea: <em>2^-4=0.0625</em>
Now that we have the size of the flea, we need to figure out how high it can jump: <em>2^3=8</em>
After we figure out the size of the flea, we need to divide 8 by .0625 because it is inverse operations to multiplication: <em>8/.0625=128</em>
Answer: The flea can jump 128 times higher than it's body size.
