Find the area of the quadrilateral ABCD , in which AB = 12 cm, BC = 6 ...
Given:
AB = 12 cm
BC = 6 cm
CD = 7 cm
DA = 15 cm

Area of Quadrilateral ABCD:
- To find the area of the quadrilateral ABCD, we can split it into two triangles, namely triangle ABC and triangle CDA.
- First, calculate the semi-perimeter of triangle ABC:
s1 = (AB + BC + AC) / 2
= (12 + 6 + AC) / 2
= 9 + AC / 2
- Using the semi-perimeter and the formula for the area of a triangle (A = √(s(s - AB)(s - BC)(s - AC))), we can find the area of triangle ABC.
- Similarly, calculate the semi-perimeter of triangle CDA:
s2 = (CD + DA + AC) / 2
= (7 + 15 + AC) / 2
= 11 + AC / 2
- Use the semi-perimeter and the formula for the area of a triangle to find the area of triangle CDA.
- Finally, add the areas of triangle ABC and triangle CDA to get the total area of quadrilateral ABCD.
Thus, the area of the quadrilateral ABCD can be found by calculating the areas of triangles ABC and CDA separately and then adding them together.
