Step-by-step explanation: For a triangle, we can find it by adding the lengths of its three sides. We can find the length of the fencing required for a triangular park by finding the perimeter of the triangle.
The area of a triangle is base x height divided by 2. A= bh/2. If a triangle base is 10 and the height 5 so the area will be 10x5 = 50 /2 = 25. The area is 25.
