Item 1 Find the area of the trapezoid by forming a parallelogram.

A drawing of a grid with a trapezoid which had 3 unit square along one side, 4 and half unit squares along the opposite side, 3 half unit squares along each non-parallel sides

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)

the correct answer is c) 2.
