Answer:
How To Calculate The Area Of A Composite Or Compound Shape (rectangles, triangles, circles).
Example 1
Calculate the area of this composite shape.
This composite shape is made up a rectangle and triangle.
First of all work out the area of the rectangle. The area of a rectangle can be found by multiplying the base length by the height:
Area of rectangle = 14x12=168 cm^2
Secondly, work out the area of the triangle. The area of a triangle can be found by multiplying the base by height and dividing the answer by 2. Now the base length of the triangle is not given but this can be calculated by subtracting the 14 cm from the 8cm to give 16 cm.So the area of the triangle is:Area of triangle = (8x12)/2=48 cm^2 So the total area of the composite shape is 168+20=188 cm ^2.
Example 2
3x10=30 cm^2
Secondly,The area of a triangle can be found by multiplying the base by height and dividing the answer by 2. Now the base length of the triangle is not given but this can be calculated by subtracting the 10 cm from the 5cm to give 16 cm.
So the area of the triangle is:Area of triangle = 4x10/2=20 cm^2 So the total area of the composite shape is 30+20=50 cm^2.
