Find the missing measurement. round your answer to the nearest tenth.

Step-by-step explanation:

Let

b-----> the base of the missing measurement of the parallelogram

we know that

The area of the parallelogram is equal to

we have

so

------> equation A

In this problem

substitute the value in the equation A and solve for b

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
