Answer 2

The equation for calculating

$P = 2L + 2W$

instead of letters L and enter the values ​​given numbers

$L = 2 \frac{1}{2}$ 

$W = 3 \frac{2}{5}$ 

1 way

$P = 2 * 2 \frac{1}{2} + 2 * 3 \frac{2}{5} \\ \\ P = \frac{2}{1} * \frac{5}{2} + \frac{2}{1} * \frac{17}{5} \\ \\ P = 1 * 5 + \frac{34}{5} \\ \\ P = 5 + 6 \frac{4}{5} = 11 \frac{4}{5}$ 

2 way

$P = 2L + 2W = 2 * (L + W) = 2 * (2 \frac{1}{2} + 3 \frac{2}{5} ) = 2 * ( 2 \frac{5}{10} + 3 \frac{4}{10} ) =$ $2 * 5 \frac{9}{10} = \frac{2}{1} * \frac{59}{10} = 1 * \frac{59}{5} = 11 \frac{4}{5}$
