We have three pairs of rectangles:
16ft × 6ft = 96ft²
2ft × 6ft = 12ft²
2ft × 16ft = 32ft²
S.A. = 2 × (96 + 12 + 32) = 2 × 140 = 280ft².
<h3>Answer: C.) 280ft²</h3>
Ok well you would use pathagorean there so A2+B2=C2
Answer : b = 8

Answer:
100(1/a + 1/b)
Step-by-step explanation:
Machine A takes a hours to make 100 bolts
- Then machine A makes 100/a bolts in one hour
Machine B takes b hours to make 100 bolts
- Then machine B makes 100/b bolts in one hour
<u>Two machines will make:</u>
- 100/a + 100/b = 100(1/a + 1/b)
bolts in one hour
