The sides of a quadrangular field, taken in order are `26 m ,27 m,7m` are `24 m` respectively. The angle contained by the last two sides is a right angle. Find the area.

Explanation

To find the area of the quadrangular field with sides 26 m, 27 m, 24 m, and 7 m, where the angle between the last two sides (7 m and 24 m) is a right angle, we can break the quadrilateral into two triangles: triangle ABC and triangle ADC.

### Step 1: Identify the triangles
We have:
- Triangle ABC with sides 26 m, 27 m, and AC (which we need to find).
- Triangle ADC with sides 24 m, 7 m, and AC.

### Step 2: Calculate the length of AC using the Pythagorean theorem
