We look at the tens place
20 is in the tens place
now look at the Ones place
6 is in the Ones place
If it is 5 or greater we round it to the next ten, if it is 4 or less we keep it the same
6 is greater than 5
The number will be rounded to 430
You can solve this problem by using the pythagorean theorem.

Where the a- and b-values represent the sides of the triangle. Since the park is a sqaure, each side is equal. This means that both the a-value and the b-value are the same. Now, you must find the c-value.
145^2 + 145^2 = c^2
21,025 + 21,025 = c^2
42,050 = c^2 *now square root each side of the equation.*
205.06 = c
The length of the diagonal line is 205 meters.
The correct choice is D.) No solution
