Question

You cut a sheet of paper along its diagonal, as shown. What is the length of the diagonal? Round your answer to the nearest tenth

Answer 1

c≈14.9 in

Explanation:

What we have is a right triangle. We can use Pythagoreans theorem to solve for the hypotenuse.

`a^2+b^2=c^2 = > c=√(a^2+b^2)` ;
`a=10` and
`b=11`

`c=√((10)^2+(11)^2)`

=>
`c=√(100+121)`

=>
`c=√(221)`

=> c≈14.9 in
