Question

A quadrilateral has sides of lengths 3cm,4cm,5cm and 'x' cm. What is the greatest possible integral value of 'x'?

Answer 1

11

Explanation:

If you think about, for any shape, no side can be greater than the sum of all the other sides. If it were equal then it would be a straight line. If it were greater then the shape can not be "closed." Based on this principle, `x<12`. The largest integral value that satisfies this is 11.
