How do you find the area of a triangle from a graph?

How Do You Calculate the Area of a Triangle on a Graph? The area of a triangle on a graph is calculated by the formula of area which is: A = (1/2) |x1 1 (y2 2 − y3 3 ) + x2 2 (y3 3 − y1 1 ) + x3 3 (y1 1 − y2 2 )|, where (x1 1 ,y1 1 ), (x2 2 ,y2 2 ), and (x3 3 ,y3 3 ) are the vertices of triangle.

What is the area of the triangle formed by the line x A y B 1 with the coordinate axes?

1/2
Comparing this with the intercept form of equation of the line x/a + y/b = 1, we have the x-intercept = a = 14, and the y-intercept = b = 6. The area of the triangle formed by this line and the coordinate axes is 1/2. |ab|.

What is the area of the triangle formed?

(i) The area of the triangle ABC can also be expressed in the following form: ∆ ABC= 12[y₁ (x₂ – x₃) + y₂ (x₃ – x₁) + y₃ (x₁ – x₂)] sq. units. on the contrary, the expression for the area of the triangle will be negative if the vertices A, B and C are taken in the clockwise direction as show in the given figure.

What is the area of triangle formed by three collinear points?

zero
Area of the triangle formed by three collinear points is zero.

How do you calculate the area?

To work out the area of a square or rectangle, multiply its height by its width. If the height and width are in cm, the area is shown in cm². If the height and width are in m, the area is shown in m².

What is coordinate axes in maths?

Definition of axes of coordinates 1 : two intersecting straight lines used as reference lines in plane Cartesian geometry. 2 : the three straight lines having a common point that are the intersections of the three coordinate planes of reference in three-dimensional Cartesian geometry.

What type of straight lines will be represented by the system of equations 2x 3 y is equals to 5 and 4 x 6 y is equal to 7?

So, the given system of linear equations will represent a pair of parallel lines.

How do you find the area of a right triangle?

The line, x axis and y axis form a right triangle, since x axis and y axis are perpendicular to each other. To find the area of the triangle, you need to know 1) the value of the x intercept (the point where the line intersects the x axis): This is the length of one side of the triangle.

What is the area of a triangle formed by x=0 y=0 and 4x+5Y=20?

Maths keeps one mentally active. What is the area of a triangle formed by the lines x=0, y=0, and 4x+5y=20? The line cuts the x-axis at (5,0) and the y-axis at (0,4). Hence the area of the triangle formed by the lines x=0, y=0, and 4x+5y=20 is = (5*4)/2 = 10 sq, units.

What is the area of 3x+4Y=a?

If you draw these lines on paper you can clearly see that these lines form a right triangle as two of them are x and y axis which are perpendicular to each other. 3x+4y=a will intersect the axes at a/3 and a /4 .the area of this triangle will be a*a /12.

What is the formula to find the area of an area?

formula to find area = (1/2) b h = (1/2) x Base x Height
