Area of Triangle - Coordinate Geometry

 The area of the triangle is option A) according to the options given in the diagram

Step-by-step explanation:

The given triangle is a right triangle with co-ordinates A(x1,y1),B(x2,y2),C(0,0)

And thus its area is given by  the formula A= ( ½) *( b* h)  where b is base of triangle and h is height of the triangle

Let Base = AC and Height = BC

The length of AC is : (x₁-0)² + (y₁-0)²

=>  

The length of BC is:  (x₂-0)^2 + (y₂-0)^2

 =>  

Hence the area is

Area = (1/2) * *

Area =

Hence, the area of the triangle is option A) according to the options given in the diagram

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
