See below...

#### Explanation:

Firstly, all of the lines with a dash are equal in length

Secondly , the area of the square is

To work out the area of the sectors, the most simplest way to do it is by using radians.

Radians are another form of measurement for angles.

1 radian happens when the radius is equal to the Arc length.

To convert to radians we do

Now the area of a sector is equal to

Where the angle is in radians.

Here the radius of the semi circles is

As we have two sectors we have another
