Answer: 213 meters.
Step-by-step explanation:
A=2(wl+hl+hw) is the formula. l = 6, w = 3.5, h = 9 for this problem.
2([3.5 x 6]+[9 x 6]+[3.5 x 9])
2(21+54+31.5)
2(106.5)
A=213
Sorry if this isn’t a great explanation. Hope this helps.

Answer:
4 + 2/3 hours
Step-by-step explanation:
For the expert,
6 hours = 1 job
For the secretary,
7 hours = 1 job
We want to figure out how much the expert gets done in 2 hours.
2 hours = x jobs for the expert.
To turn 6 hours = 1 job into this, we can multiply both sides of the equation by 2 (the number we want to get to) / 6 (the number we are at) to get
6 hours * 2/6 = 1 job * 2/6
2 hours = 2/6 jobs
Therefore, the expert does 2/6 of the job, and 1-2/6 = 4/6 of the job is left for the secretary. We want to figure out how long it takes for her to complete the job
We know
7 hours = 1 job
and want to figure out
y hours = 4/6 jobs
We can multiply both sides of the original equation by (4/7) (the number we want to get to) / 1 (the number we are at) to get
7 hours * 4/6 = 1 job * 4/6
28 /6 hours = 4/6 jobs
= 4 + 4/6 hours
= 4 + 2/3 hours
