Answer=13 feet long
This information describes a right triangle, with sides 5ft and 12ft.
a²+b²=c²
5²+12²=c²
25+144=c²
169=c²
√169=√c²
13=c
The ladder needs to be 13ft long

It's a simple question, make sure that you know that the key is 32/3, and because it's not fully divisible use the whole number (10)
3x4=12 1x12=12 6x2=12
You just need to be able to multiply the sides to equal 12. I hope that helps. :)
Cups, pints, quarts, gallons. Hope this helps :)
