A response is not possible without a diagram or more information on triangle ABC

I agree with the comment above. If this refers to the triangle in a previous problem from the student above then it would be useful if the student would refer us to that question. In the previous question the triangle was certain kind. The information from the previous question can be used to calculate the area.

yes it's from the previous question, the diagram is present there (ΔABC maps the outline of a new park. Select all the types of triangles that describe the park.) Cant send the diagram as it is not going.

Thank you Faiza A. The answer to the description of the triangle given representing the Park can be used to find the area. Check the information given with that problem and use it in the formula to calculate the area (1/2)bh. You just need the base and the height, if you have any doubts about the information you can use the distance between two points formula the calculate the lengths of the base and the height. Also you can go and recheck the comments from that previous problem about the New Park.

You didn't include the dimensions or shape of the triangle in your description. The formula for the area of a triangle is a=bh/2, where b is the length of the base line segment and h is the height of a line segment at a right angle to the base that intersects with the third vertex. If you have a right triangle, h is the length of one of the legs. Otherwise you'll need to use the pythagorean theorem to determine the height of h. Google "area of a triangle" for some examples.
