Coordinates: (-1, 4) (3, 7) (5, 2) (-1, 4)
When plotted on the Cartesian plane its diagonals of 2 times square root of 10 and 8 Times Square root of 10 will intersect each other at right angles.
Area of the quadrilateral: 0.5 times the product of its diagonals = 80 square units
When the given vertices are plotted and joined together on the Cartesian plane they will form a 4 sided quadrilateral whose diagonals intercept each other at right angles and so multiplying the lengths of the diagonals divided by two will produce an area of 80 square units.
It is just an irregular quadrilateral.
No, they do not.
A pentagon has fives sides, and a quadrilateral has four. So 2 pentagons and 1 quadrilateral have 2*5 + 4 = 10 + 4 = 14 sides altogether.
No because a quadrilateral has four interior angles that add up to 360 degrees.
A quadrilateral has 4 sides and 1 face which is its surface area.
When the given vertices are plotted and joined together on the Cartesian plane they will form a 4 sided quadrilateral whose diagonals intercept each other at right angles and so multiplying the lengths of the diagonals divided by two will produce an area of 80 square units.
Draw a line from one corner of the quadrilateral to the opposite one and calculate the areas of the two triangles created using the formula for the area of a triangle 1/2 B*H (1/2 Base " Height). To do this see the graphic in the related links. Add the areas of the two triangles together to get the total area of the quadrilateral
A trapezoid is a special case of a quadrilateral which has 1 pair of parallel sides.
It is just an irregular quadrilateral.
Too many dimensions have been given to work out an answer.

No a quadrilateral can't have 3 obtuse angles and 1 right angle because if a polygon did have 3 obtuse angles and 1 right angle then it would not even be a quadrilateral.
The 4 sided quadrilateral will form a right angled trapezoid when plotted on the Cartesian plane with parallel sides of 7 units and 9 units with a height of 6 units. Area of trapezoid: 0.5*(7+9)*6 = 48 square units.
yes
No, they do not.
A trapezium is a quadrilateral (has four sides). Two sides are parellel, but the other two are not. To find the area of it, the formula is: 1/2 h(a+b)
