Question

What is the length of side IJ in the diagram? A. 5.4 B. 5 C. 6 D. 4.5

Answer 1

All i know is that it isnt 5.4

I found the answer its 4.5 how i got this is how

So this shape is a prismoid 

To find the length of the side in the middle you have to add

So, IJ= DA + FG and divide the whole thing by 2
IJ=6+3/2
=4.5

Answer 2

Answer:

Option D. 4.5

Step-by-step explanation:

In the given diagram FGAD is the trapezoid with the given sides FG = 3 units and AD = 6 units.

Now we have to calculate the Median IJ.

Since median of a trapezoid is represented by the formula = $\frac{1}{2}(FG + AD)$

Therefore, median IJ = $\frac{1}{2}(3+6)$

= $\frac{9}{2}$

= 4.5

Therefore, Option D. 4.5 will be the answer.
