Answer:
12
Step-by-step explanation:
(6)² = 3x
then x= 36/3
x= 12
Draw a square with side length of 4. All four angles are 90 degrees and all four sides are 4.
Then draw a rectangle with length of 9 and with of 2. All four angles would be 90 degrees, but the proportion of the 2 sides are different when compared to the sides of the square.
28.6 / 89.4 = 0.75 / x
cross multiply
28.6x = 67.05
x = 67.05 / 28.6
x = 2.34 <==
