#1
- B²=15²-7²
- B²=225-49
- B²=176
- B=13.26(exact)
- B=13.3(approx)
#2
- B²=17²-7²
- B²=289-49
- B²=240
- B=15.49(exact)
- B=15.5
#3
- H²=20²+14²
- H²=400+196
- H²=596
- H=24.41(approx)
- H=24.4(exact)
#4
- B²=6²-3²
- B²=36-9
- B²=27
- B=5.196(exact)
- B=5.2(approx)
(A ∩ B) means "A intersection B". Your problem statement tells you the intersection contains
{3, 4}
