solve it this way
[Area of Trapezium - Area of the left Triangle - Area of the right triangle]
=49/2 - 12/2 - 12/2
[Area of Trapezium - Area of the left Triangle - Area of the right triangle]
=49/2 - 12/2 - 12/2

Its a isoceles rt angled triangle.
1/2*5*5.
Since coords are given, it would have been a good strategy to check what is the length of the sides. since nothing else was working

I have an easy way to solve this problem...
Make a rectangle out of the triangle and then subtract the area of the three small triangles.
We get:
Area of rectangle = 7 * 4 = 28
Area of bottom right triangle = (3 * 4) / 2 = 6
Area of bottom left triangle = (3 * 4) / 2 = 6
Area of top triangle = (7 * 1) / 2 = 3.5
28 - 6 - 6 - 3.5 = 12.5
