Point D is the in center of triangle ABC. Write an expression for the length x in terms of the three side lengths AB, AC, BC. Hint: Use areas of triangles...A=1/2bh

 Expression representing the length 'x' will be, .

Use the hint → Area of the large triangle = sum of the small triangles inside the larger triangle

Area of ΔABC =

Area of ΔADC =

Area of ΔBDC =

Area of ΔADB =

Since, Area of ΔABC = Area of ΔADC + Area of ΔBDC + Area of ΔADB

    Therefore, expression representing the length 'x' will be .
