Answer 1

Hey bro, this is your answer

Answer 2

HEY MATE HERE IS YOUR ANSWER--

( ͡°╭͜ʖ╮͡° )

☛TAKE ONE SIDE OF RECTANGLE X AND TAKE SECOND SIDE 2X

☛ PERMIETER OF OF RECTANGLE

$2(l + b)$

☛L= X

☛B= 2X so , putting it in formula

80= 2(x+2x)

$80 = 2 \times 3x \\ \\ \frac{80}{2} = 3x$

$40 = 3x \\ \\ \frac{40}{3} = x$

⋙13 .3 m

☛ one side=x= 13.3

☛ another side =2x= 13.3×2= 26.2

$area \: of \: perimeter = l \times b \:$

☛so the area is

☛13.3× 26.2

⋙ 384.46 m²
