Answer 2

Step-by-step explanation:

Very easy question

We and see that it is a square of dimension 70 cm

the midpoint of the dimensions of the square can be marked as points A,B,C,D

We observe that each of the line becomes a radius of 35cm each for the half semicircle being formed

There are 4 of them so it becomes a circle only of radius 35 cm

hence area of circle is πr^2

= 22/7 * (35*35) cm^2

= 22*35*5 cm^2

= 3850 cm^2

Hence area of square = 70*70 = 4900 cm^2

Therefore area of shaded region = 4900-3850

= 1050 cm^2
