Answer:
Step-by-step explanation:
Find the area of the square - area of 4 sectors
We'll use the formula to find one sector area
where r is the radius of one sector and x is the angle in radians
Since each angle is in a square, the angle of the sectors is 90 degrees.
Convert degrees to radians
The radius of one sector is given by 70mm/2=35mm
One sector area:
Area of all 4 sectors:
Area of the square:
Hence, Area of square - 4 Sectors:
