Answer:
19.21m is the diagonal
Step-by-step explanation:
We are looking for the diagonal, which makes it the hypotenuse of a right triangle, with the legs being 15 and 12
We can use the Pythagorean theorem
a^2 + b^2 = c^2
12^2 + 15^2 = c^2
144 +225 = c^2
369 = c^2
Take the square root of each side
sqrt(369) = sqrt(c^2)
19.209 =c
19.21 m = c
