The area of the rectangle is changing at
0.75 sq.cm/min
Let
x
and
y
be the base and height of the rectangle.
x
=
0.5
cm is constant :. dx/dt=0#. Area of the rectangle
is
A
=

⋅
y
. Differentiating both sides we get

Answer:
16'.
Step-by-step explanation:
A square has 4 equal sides so it is 4 * 4' = 16'.
13.9%.
7.2 x 10^9 = 7,200,000,000.
Since 1 billion = 1,000,000,000 out of these 7,200,000,000 do not have access to clean water, we find the percent by taking:
1,000,000,000/7,200,000,000 = 10/72 = 13.9%
