Answer:

72cm²

Step-by-step explanation:

perimeter= 2(l+w)

36 = 2(l+w)

36/2 = l+w

18 = l+w

since, l is twice as w

18= 2w + w

18 = 3w (we can add since all the variables, and exponents are same)

18/3 = w

6= w

NOW,

w=6 and l is equal to twice as 6

so l=12

area= l×b

= 12×6 = 72cm²

hope this helps. It was toooo long

Answer:

-2

Step-by-step explanation:

$Rule(s): a\frac{b}{c} = \frac{a \cdot c + b}{c}, \frac{-a}{b}=-\frac{a}{b}, \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c} \\2\frac{2}{3}=\frac{2\cdot 3+2}{3}\\=\frac{8}{3}\\=\frac{-\frac{8}{3}}{\frac{4}{3}}\\=-\frac{\frac{8}{3}}{\frac{4}{3}}\\=\frac{-8\cdot \:3}{3\cdot \:4}\\= \frac{-24}{12}\\= -2$
