Answer:
288 cm^2
Step-by-step explanation:
The diagonal of the square is 24 = 2 *12
We can use Pythagorean theorem to solve.
Let s= side length of the square
s^2 + s^2 = 24^2
2s^2 = 24^2
2s^2 =576
Divide each side by 2
2/2s^2 =576/2
s^2 = 288
Take the square root each side
sqrt(s^2) = sqrt(288)
s = 16.97056275
s = 16.97 cm
We want to find the area
A =s^2
A = 16.97 ^2
A = 288 cm^2
N(n-9) = 22
n^2-9n = 22
n^2-9n-22= 0
find 2 numbers that add to -9 that multiply to -22
(n-11)(n+2)
n-11=0, n+2=0
n=11, n=-2
