Hello Fellow Army!~
This is a right triangle. To find the length of the hypotenuse a^2 + b^2 = c^2.
21^2 + 18^2 = c^2
441 + 324 = c^2
765 = c^2
27.66 km
Answer:
It is not a polynomial. It is a trinomial. Polynomials have 4 or more terms
The area of the square is side^2
1536=s^2
Square root of 1536=39.19
Side length =39.19
