Let
A(2,5)
B(13,11)
C(13,5)
using a graph tool
see the attached figure
area of triangle=AC*BC/2
distance AC
d=√[(y2-y1)²+(x2-x1)²-----> d=√[(5-5)²+(13-2)²---> d=√[11²]
dAC=11 units
distance BC
d=√[(y2-y1)²+(x2-x1)²-----> d=√[(5-11)²+(13-13)²---> d=√[-6²]
dBC=√36 units-----> dBC=6 units
area of triangle=AB*BC/2-----> 11*6/2----> 33 units²
the answer is
33 units²

Answer:
Step-by-step explanation:
A is on the same point on the x-axis as B and the same point on the y-axis as D
- Therefore, the coordinate of A is (0,0)
C is on the same point on the x-axis as D and the same point on the y-axis as B.
- Therefore, the coordinate of C is (a,a)
We are to determine the slope of the line joining A to C.
