Area of composite figures

In order to find area of composite figures, you need to break it down part by part.

For example see the example drawn.

We have a semi circle and we have a square.

When we break it down we take the semi-circle first.

To find the area of a semi-circle you do:

.

We know that the radius is 5 cm

So we do

.

Next we conquer the square:

.

We know that a square is symmetric hence:

.

Finally we sum them all together to get the composite area:

.

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
