The perimeter of the square is: 
ft
Step-by-step explanation:
The picture is attached with the answer.
the diagonal of a square divides it into two right angled-triangles.
We can use one of the triangle to find the length of side as the diagonal will be the hypotenuse of the triangle
Let a be the side of the square, then according to Pythagoras theorem
Dividing both sides by 2
Taking Square root on both sides
Now,
Hence,
The perimeter of the square is: ft

Answer:
4 coins
Step-by-step explanation:
First, let's find out how much she gave the teller:
2($20)=$40
Now, let's find out how much change the teller owes her:
$40.00-$39.63=$0.37 or 37 cents
The largest coin (under 37 cents), is a quarter which is worth 25 cents...
37-25=12 cents
The largest coin (under 12 cents), is a dime which is worth 10 cents...
12-10=2
The largest coin (under 2 cents), is a penny which is worth 1 cent...
2-1=1
And one more penny...
1-1=0
Therefore the fewest amount of coins she can get in change are a quarter, a dime, and two pennies, which is 4 coins.
To find the Area of a triangle your equation is A=1/2(hb), your area is 16
