too lazy but that's the exact value
The one that look exactly the same it the third one
88=4*22=> sqrt88=2sqrt22
sqrt22 is approximately sqrt25=5
so 4 < sqrt22 < 5
8 < 2sqrt22 < 10
8 < sqrt88 < 10
The answer would be D because 100 Centimeters equal 1 meter so therefore it would be 200 day's of knitting
