What is the area of triangle ABC with vertices A(x¹,y¹), B(x²,y²)and C (x³,y³)??????????<br>​
AlexFokin [52]

Answer:

Area = \frac{1}{2}|x_1(y_2 - y_3)+x_2(y_3 - y_1)+x_3(y_1 - y_2)|

Area = 2\ units^2

Explanation:

Given

A = (x_1,y_1)

B = (x_2,y_2)

C = (x_3,y_3)

Required

Determine the area

The area of a triangle is :

Area = \frac{1}{2}|A_x(B_y - C_y) + B_x(C_y - A_y) + C_x(A_y - B_y)|

By substituting values for the x and y coordinates of A, B and C;

We have:

Area = \frac{1}{2}|x_1(y_2 - y_3)+x_2(y_3 - y_1)+x_3(y_1 - y_2)|

So:

For instance

A = (0,3)

B= (2,1)

C = (2,3)

The area is:

Area = \frac{1}{2}|0(1-3) + 2(3-3) + 2(3-1)|

Area = \frac{1}{2}| 2*0 + 2*2|

Area = \frac{1}{2}| 0 + 4|

Area = \frac{1}{2}|4|

Area = \frac{1}{2} * 4

Area = 2\ units^2

(23.4m)(14m) rounded off to the correct number of significant figures
VARVARA [1.3K]

The value of the given expression up to correct significant figures is 330 m^2.

  • The rule that applies for the multiplication and division is :

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

  • The rule that applies for the addition and subtraction is :

The least precise number present after the decimal point determines the number of significant figures in the answer.

Given:

The expression: (23.4m)(14m)

To find:

The answer up to correct a number of significant figures.

Solution

Number of significant figures in '23.4' = 3

Number of significant figures in '14' = 22

=(23.4m)(14m)\\=(23.4m)\times (14m)\\=327.6 m^2

The number with the least significant figures is '14' is 2, so the answer will be reported up to 2 significant figures:

=327.6 m^2\approx 330 m^2

Number of significant figures in '330' = 3

The value of the given expression up to correct significant figures is 330 m^2.
