Areas are measured in km2, not in km.
Answer:
43.667 years
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)ⁿ
Step 1: Define variables
A = 10,000
P = 5,000
r = 0.016
n = unknown
Step 2: Substitute variables
10,000 = 5,000(1 + 0.016)ⁿ
Step 3: Solve for <em>n</em> time
2 = (1.016)ⁿ

Good Question!
So since we know that a square is exactly the same all the way around we can assume that both diagonals in the square are the same. This means that they form a right triangle in the middle with two legs of 3.75!
So to find the side of the triangle we use a^2 + b^2 = c^2
3.75^2 + 3.75^2 = c^2
28.125 = c^2
<span>√(28.125) = c
</span>c = 5.3
Now finally we just square 5.3 again to find the area of the square and it's 28.1mm^2!
So the answer is the third one! hope this helps!
Substitute the value of b = -2 to the expression
