The rectangle area is 98. So if you split it in half, you would get 2 squares. Half of 98 is 49.
If it is now a square, you now simply know, that 7*7=49. Meaning that The sides of the square are 7 each.
7 times the 4 sides equals 28. So the perimeter of one square is 28.
So this is a Pythagorean problem where
A^2+b^2=c^2
a is 2
X is b
5 is c
Plug that into the equation and get
4+b^2=25
B^2=21
B=sqrt(21)=4.6kilometer
Answer:
its suposed to be written [(40+5)-3^2]÷9·2
so the answer would be C.8
Step-by-step explanation:
first do whats in the brackets but inside the ark looking brackets first
[(40+5)-3^2]÷9·2
will be [45-3^2]÷9·2
and then you do the rest of the brackets but first you square 3 sitch will be come 9
so [45-9]÷9·2
witch will become
36÷9·2
now divide by 9 and get
4·2
witch is going to be
8
therefore the answer is C.8
