You add together the lengths of its sides.
No. A triangle has three sides, a quadrilateral has four.
Assuming you mean perimeter (not pirimeter) and triangle (traingle) you need to sum together the lengths of the three sides.
The perimeter of a quadrilateral is 'side + side + side + side = perimeter'. If the quadrilateral is a square, you can simplify this to 'side x 4 = perimeter'.
Use Pythagoras' theorem to find the hypotenuse which works out as 25cm Perimeter = 25+24+7 = 56cm
A quadrilateral is a four sided figure, so sum the lengths of its four sides.
If you want the perimeter of a quadrilateral, then finding the midpoints is a complete waste of time! Simply add together the lengths of the four sides.
It is called the perimeter and is the sum of the lengths of its three sides.
Which quadrilateral? What is x?
88/4=22
Unless it is a rhombus (or square) you cannot.
No...
It is not a quadrilateral because quadrilaterals are figures that have four sides (thus the use of quad meaning four). A triangle only has three
