Answer:
√869 ≈ 29.48 square units
Step-by-step explanation:
The vector cross product is ...
(3·1 -5·4, -6·1 +2·4, 6·5 -2·3) = (-17, 2, 24)
The area is the magnitude of this vector, so is ...
√((-17)² +2² +24²) = √(289 +4 +576) = √869 ≈ 29.48
The area is about 29.48 square units.
It would be the area of the big square minus the area of the small square.
24
4! = 4*3*2*1 = 24
24 numbers can be formed
If you are looking for an equation, then it would be 25 < x.
