What is the area of the PolyGram with the height being 16cm and 7 cm on one side. Other side 7, 5, 4
To calculate the area of a polygon, you can split it into triangles and calculate the area of each triangle separately.
In this case, the polygon has a height of 16cm and three sides of lengths 7cm, 5cm, and 4cm.
First, calculate the area of the triangle with sides of lengths 7cm, 5cm, and a height of 16cm:
Area = 1/2 * base * height
Area = 1/2 * 5 * 16
Area = 40 square cm
Now, calculate the area of the triangle with sides of lengths 4cm, 5cm, and a height of 16cm:
Area = 1/2 * base * height
Area = 1/2 * 4 * 16
Area = 32 square cm
Now, add the areas of the two triangles together to get the total area of the polygon:
Total Area = 40 + 32
Total Area = 72 square cm
Therefore, the area of the polygon with a height of 16cm and sides of lengths 7cm, 5cm, and 4cm is 72 square cm.
