Answer:
To find the "?" we can just simply subtract the side of the two rectanges and divide it by two
43.18 - 25.4
=17.7
17.7/2 ( We divide it by two becuz it's the sum of the two "?" height)
=18.8
the height of the "?" On the vertical axis is 18.8
27.94 - 20.3
=7.64
7.64/2
=3.82
this the height of the "?" on the horizontal axis is 3.82
hope this helps
