The answer is the square root of 101.75 Assuming that the sandwich Is a square, after cutting it diagonally, it turns into 2 triangles. To look for a missing length of a triangle, you use Pythagorean’s theorem a^2+b^2=c^2 Since c is 12 and a is 6.5 you just square 12 and square 6.5 144 42.25 Subtract it 101.75 You then have to find the square root of it. You can leave it as it is as √101.75 or just solve for it and round it to 10.09
So, 4.01 is less than 4.1. Think of it as 4.10 and 4.01, 1 is less than 10. One you could have put is 4.101, because it is more than 4.1 and less than 4.11
Whats the model because 7/9 × 3/4= 7/12 which also equals to 21/36 as 7/12 is the simplified version of 21/36 but then for c 4×9 =36 so I'm a bit confused my self but here's a bit of a start
