Question

Sum of the lengths of four sides of a quadrilateral is called​

Answer 1

Sum of the lengths of four sides of a quadrilateral is called​ its PERIMETER

Quadrilateral is a four-sided polygon.

A closed shape formed by more than two coplanar segments is called a polygon.

Each segment, called a side, intersects two adjacent segments at their endpoints, called vertices. No two adjacent segments are collinear.

The perimeter of a polygon is the sum of the lengths of all its sides.

A polygon with 4 sides is Quadrilateral

Hence, Sum of the lengths of four sides of a quadrilateral is called​ its PERIMETER

Answer 2

Answer:

The sum of lengths of four sides of a quadrilateral is called its perimeter

Step-by-step explanation:

A quadrilateral is a four sided polygon.

For every polygon, the sum of the length of its all sides is its perimeter

So, for a quadrilateral, it has four sides, so the sum of its four sides is called its perimeter.
