Area of the pentagon is
Explanation:
It is given that AC = 8 cm, AD = 15 cm, BF = 3 cm, CG = 7 cm and EH = 5 cm.
From the figure the area of the pentagon can be determined using the formula,
Area of the pentagon ABCDE = Area of ΔABC + Area of ΔACD + Area of ΔAED
Area of ΔABC =
Substituting the values, we get,
Area of ΔABC =
Similarly,
Area of ΔACD =
Area of ΔAED =
Now, Substituting all the values of the triangles in the formula, we have,
Area of the pentagon ABCDE = Area of ΔABC + Area of ΔACD + Area of ΔAED
Area of the pentagon ABCDE =
Thus, the area of the pentagon is
