I cant answer if there is no info
So whats the rest of this question? its uncompleted.
Here's one way:
A=WxL
So in this case, it's 2x5
You would draw the rectangle, label one side 2 in. and the other 5 in. Draw an arrow from each no./side and put x underneath the line so that its 2 —x— 5 (2, line, x, line, 5. With x under line)
Omg we have the same bed frame bunk bed thing Hahah
