Answer:
Using the pythagoras theorem
Let's say the hypotenuse of the first diagram is b
b²=4²+2²
b²=16+4
b²=20
b=✔(20)
In finding x , b will be the opposite and the x be the hypotenuse
x²=(✔20)²+7²
x²=20 +49
x²=69
x=8.31
Answer:
The length of the fence that encloses the park is 400 m
Step-by-step explanation:
step 1
Find the length of the square city park
we know that
The area of a square is

where
b is the length side of the square
we have

substitute and solve for b

take square root both sides

step 2
Find out the length of the fence that encloses the park
we know that
The length of the fence is equal to the perimeter of the square city park
The perimeter of the square is

we have

substitute

therefore
The length of the fence that encloses the park is 400 m
So you have to do 2×5 because the dogs tail is 2 inches long and is grows 5 inches or something every year. So 5×2=10
