Question

What is the smallest whole number larger than the perimeter of any triangle with a side of length 5 and a side of length 19?

Answer 1

48

Explanation:

The maximum third side length of a triangle with two sides 5 and 19 is 5+19-1=23. Therefore, the maximum perimeter of a triangle with the two side lengths given is 5+19+23=47.

The smallest whole number larger than this is 48.
