Answer 2

If I say the following (\(\Downarrow\)) then you will agree, right?




\(\huge\color{magenta}{ \rm L }\)
\(\normalsize\color{ slate }{\Huge{\bbox[5pt, lightcyan ,border:2px solid black ]{ \color{lightcyan}{\Huge\frac{~~~~~~~~\frac{~}{~~~\frac{~\frac{}{}~}{~\frac{~}{~}}~~~~}~~~}{~\frac{\frac{~}{~\frac{~\frac{}{~}}{~}}~~}{~}~~} } }}}\) \(\huge\color{darkviolet}{ \rm W }\)


\(\huge\color{blue}{ \rm Area = \color{magenta}{ \rm L }\times\color{darkviolet}{ \rm W } }\)

Answer 3

so, same thing is here, except that your L is 4√10, and your W is 3-√10

Answer 4

Mhm okay

Answer 5

So in this case

\(\huge\color{blue}{ \rm Area = \color{magenta}{ \rm 4\sqrt{10} }\times\color{darkviolet}{ \rm \left(3-\sqrt{10}\right) } }\)

Answer 6

all you got to do, is to multiply this.

Answer 7

Would it be 12/10-40?

Answer 8

no, .... how did you come up with this expression?

Answer 9

4 times 3 then 4 times 10

Answer 10

Then it would have to be 12/10-10 or whatever

Answer 11

4√10 • (3 - √10) =
(4√10 • 3) - (4√10 • √10)=
(12√10) - (4√100)=
12√10 - (4•10)=
12√10 - 40

Answer 12

I mean your question doesn't make sense because the width is negative, but...
