Answer:
42 = <em>l</em>
21 = <em>w</em>
Step-by-step explanation:
{l = 2<em>w</em>
{126 = 2<em>w</em> + 2<em>l</em>
126 = 2<em>w</em> + 2[2<em>w</em>]
126 = 2<em>w</em> + 4<em>w</em>
126 = 6<em>w</em>
21 = w [Plug this back into both equations to get the length of 42]; 42 = <em>l</em>

Answer: By cross multiplication.
Step-by-step explanation: Given product is 3 × 292.
We know that after simple multiplication, we get 3 × 292 = 876.
Now, to check division with multiplication, either we need to divide 876 by 3 to get the answer 292,
or
we need to divide 876 by 292 to get the answer 3.
We will do that as follows -
![\dfrac{876}{3}=292~~~\textup{and}~~~\dfrac{876}{292}=3.](https://tex.z-dn.net/?f=%5Cdfrac%7B876%7D%7B3%7D%3D292~~~%5Ctextup%7Band%7D~~~%5Cdfrac%7B876%7D%7B292%7D%3D3.)
Thus, doing cross-multiplication, we arrive at our conclusion.
