A rectangle is 12 meters wide and 9 meters long. How long is it’s diagonal?

Also what am I looking for the hypotenuse or the leg

Respuesta :

Answer:

The diagonal is 15 meters

Step-by-step explanation:

  Right triangle.     You are looking for the hypotenuse because the diagonal is the longest side.

a² + b² = c²

9² + 12² = c²

81 + 144 = c²

225 = c²

[tex]\sqrt{225}[/tex] = 15
