Area = 0.5*base*height
πr2where π=3.14and r is radius
by the w x h x lenght
In regular quadrilaterals, it's length times width.
Area = Length x Width Perimeter = (2 x Length) + (2 x Width)
H2O
pentagon
The chemical formula of octane is C8H18.
Area = 0.5*base*height
Pounds x 0.454 (or 0.453592374) = kilograms
Inches x 0.0254 = meters
πr2where π=3.14and r is radius
the fourmula is 2n square n= # of shells
Soda is sodium hydroxide (NaOH) or sodium carbonate (Na2CO3).
by the w x h x lenght
In regular quadrilaterals, it's length times width.
There is no such word as "fourmula". I assume that you meant formula. However, there is still no "the formula". The formula for its perimeter is simple: perimeter = sum of the sides. But, depending on its shape, there will be simple or very complicated formulae for the area, angles and so on.
