Question

Ernesto takes a sheet of paper and makes a diagonal cut from one corner to the opposite corner, making two triangles. The cut he makes is 20 inches long and the width of the paper is 16 inches. What is the paper's length?

Answer 1

3`1

Explanation:

Answer 2

Answer: 12 inches

Explanation:

The 20 inches is the hypotenuse whereas 16 inches is the height of the triangle respectively.

So,

let keep the paper's length as x inches.

20² = 16² + x²

x² = 20² - 16²

x =
`\sqrt{20^(2)-16^(2) }`

x = 12

I am not sure if this is right because i have never done a sum in inches before but I hope this helps sorry if it is not right.
