Answer:
Height = 5.6cm
Step-by-step explanation:
Area = 1/2bh
b = 10cm, area = 28cm^2
:- 28 = 1/2 × (10)h
28 = 5h
h = 28/5
h = 5.6cm
(You copied 'upper left' twice, and you left out 'lower right'.
But we know what you mean.)
If those are the corners of the wall, then they're ALL in the plane of
the wall (coplanar with it).
Its impossible for there to be 2.5 children so im assuming you meant 25.
therefore
25= 100%
100/14= 7.1
7.1% of Mr. carters class were girls
