Astudent measured the area of a bulletin board as 2.1 m squared. to find it’s area in square feet, he multiplied 2.1 by 3.28, getting an answer of about 6.9 ft squared. explain the student’s error. what is the correct area in square feet?

For this case we have that the conversion from feet to meters is given by:

Then, converting the specified measure we have:

Rewriting we have:

the student’s error is: He forgot to square

the correct area in square feet is 22.6feet².

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
