What is the equation of the plane that contains the triangle shown in the diagram *answers in question*

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
