if radius of circular part is 25m then no touch eachother
now are of left =area of square-4.area of corner part
=50^2-4x1/4pi (25)^2
=2500-22/7x625
2500-1964.28=535.72m^2
now are of left =area of square-4.area of corner part
=50^2-4x1/4pi (25)^2
=2500-22/7x625
2500-1964.28=535.72m^2

Given: ABCD is a square such that whose side is 50m. cows are tied at the corner of the square form a quadrant so, the radii = 50/2 = 25m. area of left ungrazed field = area or square _ area of 4 quadrant. = side ×side _ 4×1/4 pie r×r = 50×50 _ 4×1/4 × 22/7 ×25×25 =2500_ 1964.28 =535.72 (approx) so, will be left ungraze is 535.72
