Given parallelogram ROCK and KR = 57, RO = 3, find CK.
R
K

The length of CK =  3 units.

Step-by-step explanation:

Given parallelogram ROCK and KR = 57 units , RO = 3 units

A parallelogram is a kind of quadrilateral with following characteristics:

So , if ROCK is a parallelogram, then

RO = CK [Opposite sides are congruent]

i..e CK = RO= 3 units

That means , the length of CK =  3 units.

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
