Martin needs to place caution tape across both diagonals of a rectangular door that is broken in his store. if the dimensions of the door are 3 feet by 7 feet, how many feet of caution tape will he need?

Respuesta :

Answer: He will need 15.24 feet of caution tape.

Step-by-step explanation:

Since we have given that

Length of door = 3 feet

Width of door = 7 feet

So, Diagonal of door is given by

[tex]sqrt{3^2+7^2}\\\\=\sqrt{9+49}\\\\=\sqrt{58}\\\\=7.62\ feet[/tex]

Since there are 2 diagonals of a rectangular door.

So, Length of caution tape he would need is given by

[tex]2\times 7.62\\\\=15.24\ feet[/tex]

Hence, He will need 15.24 feet of caution tape.
