(a+b+c)/2. this is your answer. if it had the numbers i would solve it fully, but it only has variables.
ANSWER: B)198
Have a great day!

<span>We can
use the Pythagorean Theorem (A² + B² = C²) to solve for the lengths of the
sides. We know that the diagonal, C, is 30 meters long, so C² = 900 meters.
We know that since the park is square, A² + B² = 2A² = 2B²
900 = 2A²
A^2 = 450
Taking the square root of 450, we find that the lengths of A and B are
roughly 21.2 meters.</span>

Answer:
x= -3
Step-by-step explanation:
7+
= 5
21+2x=15
2x=-6
x= -3
Standard form is (y=x+n) *n=number* y=-3x+2
