If you mean vertices of: (-1, -1) (-1, 3) and (5, -1) then when plotted on the Cartesian plane it will form a right angle triangle with a base of 6 units and a height of 4 units. Area of triangle: 0.5*6*4 = 12 square units

AnswerFind the volume of a square pyramid with a height of 13 m and base edges of 9 m.
Yes they could. The only requirement is that if you add any two sides together they are longer than the third. 19 + 13 > 14; 19 + 14 > 13, and 13 + 14 > 19, so those sides can make a triangle.
1 Angles are measured in degrees, minutes and seconds 2 Angles greater than 0 but less than 90 degrees are acute 3 Angles of 90 degrees are right angles 4 Angles greater the 90 but less than 180 degrees are obtuse 5 Angles greater than 180 but less than 360 degrees are reflex 6 Angle of 360 degrees is a full rotation 7 Triangles are 3 sided polygons 8 Triangles have 3 inside angles that add up to 180 degrees 9 Triangles have 3 outside angles that add up to 360 degrees 10 Triangle that is scalene has 3 different acute angles 11 Triangle that is a right angle triangle has a 90 degree angle and 2 acute angles 12 Triangle that is obtuse has 1 obtuse angle and 2 acute angles 13 Triangle that is isosceles has 2 equal base angles and 2 equal sides 14 Triangle that is equilateral has 3 equal inside angles and 3 equal sides 15 Triangles have no diagonals 16 Triangles will tessellate leaving no gaps or overlaps 17 Triangle's area is 0.5*base*perpendicular height 18 Triangle's perimeter is the sum of its 3 sides 19 Triangle as a right angle triangle is subject to Pythagoras' theorem 20 Triangles are subject to the rules of trigonometry 21 Triangles are the corner stones of all other polygons
Area of a triangle = 1/2*base*height = 1/2*(6-2y)*13 = (3-y)*13 = 39-13y
The area is 117 units2
Triangle B The area of a triangle is the length of the base times the height divided by two. Triangle A has base 13 m and height 5 m so we have (13 * 5) / 2 = 32.5 square meters. Triangle B has base 9 m and height 8 m so we have (9 * 8) /2 = 36 square meters. Therefore Triangle B has the greater area.
An equilateral triangle with a height of 20 has a base of 23.1 (23.09401), not 15. If the base is 15 then the height will be 13 (12.99038).
It is: 0.5*13*6 = 45 square units
The base of the triangle is 13 units because 0.5*13*9 = 58.5 square units
Area of a triangle = 1/2*base*height. Therefore the area of the triangle = 1/2*4*13 = 26 square feet.
The area of triangle is : 71.5
The area is calculated as the base times the height divided by 2. In this example, the answer is 52 units squared.
32.5 units2
Area = 0.5*13*17 = 110.5 square yards
The area of a triangle is (1/2)(base)(height). In the case of a right triangle, one leg is the length of the base and the other leg is the height.The area in this case is (1/2)(13)(2) = 13 square units.
