Solve a/b=c/d for a/c

c=b-d

       a

Step-by-step explanation

a ( b − c ) = d Divide by a on both sides. a ( b − c ) a = d a b − c = d a Subtract b from both sides. b − b − c = d a − b − c = d a − b Reverse signs. ∴ c = − ( d a − b ) = b − d a

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
