Answer:

522 m^2

Step-by-step explanation:

I've circles the numbers that you actually need to solve this problem.

First, find the area of the bigger rectangle by multiplying the length and width.

24*21=504

Then find the area of the smaller rectangle the same way

3*6=18

then add them to get the total area

504+18=522

Is it ever possible that sin (A+B)= sin⁡ A+sin⁡ B? If so, explain how. If not, explain why not.

Contact [7]

The formula for the sine sum is

$\sin(a+b)=\sin(a)\cos(b)+\cos(a)\sin(b)$

So, equation

$\sin(a)\cos(b)+\cos(a)\sin(b) = \sin(a)+\sin(b)$

Cannot be solved with standard ways. However, we can build special cases to make it work.

The most trivial example would be A=B=0. In this case, we have

$\sin(0+0)=0 \sin(0) = 0,\quad\sin(0)+\sin(0)=0+0=0$

If we work on this idea a little bit, we can produce examples like

$A=2k_1\pi,\quad B=2k_2\pi$

And again we have

$\sin(A+B)=\sin(2\pi(k_1+k_2))=0$

$\sin(A)+\sin(B)=\sin(2k_1\pi)+\sin(2k_2\pi)=0+0=0$

So, yes, it is possible that $\sin(A+B)=\sin(A)+\sin(B)$ , although solving the equation directly would be quite difficult.
