First add the perimeter
3.65m + 2.24m + 2.24m + 3.65m + 2.57m = 14.35 m
then convert meters to centimeters (just move the decimal place two places to the right)
answer is 1,435 cm

Answer: $\bold{x^2-\dfrac{181}{13}xy+12y^2=0}$

<u>Step-by-step explanation:</u>

$\tan \theta =\dfrac{y}{x}\quad \longrightarrow \theta=\tan ^{-1}\bigg(\dfrac{y}{x}\bigg)$

$\text{Given:}\quad \theta =\tan^{-1}\bigg(\dfrac{1}{13}\bigg)\quad \longrightarrow x=13,y=1$

Insert x = 13 and y = 1:

x² + 2hxy + 12y² = 0

(13)² + 2(13)(1) + 12(1)² = 0

169 + 26h + 12 = 0

26h + 181 = 0

26h = -181

$h=-\dfrac{181}{26}$

$\text{Insert:}\ h=-\dfrac{181}{26}$

$x^2 + 2\bigg(-\dfrac{181}{26}\bigg) xy + 12y^2 = 0$

$\bold{x^2 -\bigg(\dfrac{181}{13}\bigg) xy + 12y^2 = 0}$
