A rectangle has an area of 102cm². The length of the rectangle is 17cm. What is the perimeter of the rectangle?
enyata [817]

<u>Solution:</u>

Area of the rectangle = 102cm²

Length of the rectangle = 17cm

∴ Breadth of the rectangle = Area/length

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 102cm²/17cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 6cm

<u>To Find the Perimeter :</u>

Length of the rectangle = 17cm

Breadth of the rectangle = 6cm

∴ Perimeter of the rectangle = 2( l × b)cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 2( 17 × 6)cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 2 × 102 cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 204 cm

a 22 gram sample of a substance thats used to preserve fruit and vegetables has a k value of 0.1011. find the half life rounded
Bess [88]
K value = natural log (.5) / half-life
half-life = natural log (.5) / k value
half-life = -.693147 / 0.1011
half-life = <span> <span> <span> 6.8560534125 </span> </span> </span>

I'd say the k value should be negative AND it should have units.
