Question

Garrett was given a sculpture that needs to have lights put around the outside only. How many inches of lights will be needed?

Answer 1

Answer:

204 in

Step-by-step explanation:

I can't really explain this other than that you have to add all the sides and the outside of this shape. For the hypotenuse you use the formula $a^2+b^2=c^2$. Now just fill in what you know.

$12^2+9^2=x^2\\144+81=x^2\\225=x^2\\x=15$

So we have:

length: 12in

base: 9in

hypotenuse: 15in

So now we do 12+15+9+15+12+15+9+15+12+15+9+15+12+15+9+15. Once we do all that we get 204 in.
