The area of each part is given as follows.
Steps of construction:
With a radius of scale 2 cm draw a circle.
Extend the line of radius to form a diameter.
Draw a perpendicular line at the distance of 2 cm from one end of the diameter of the circle.
A point where the above lines intersect is the center of the circle.
Hence the required two mutually perpendicular line passing through the centre.
As we know that, the one-forth part of the circle is called as the quadrant of the circle, it's area is given by,
Area of quadrant = πr²/4
r = 2 cm
= π × 2²/4
= π × 4/4
= π
Therefore, the area of each part is π = 22/7 = 3.14
