EXAMPLE and Question: Area of composite figure. Combine like terms•
and write the final answer WITHOUT UNITS. (Round to nearest tenth.)
12.5cm
A = r22
= 3.14 x 12.52 - 2
= 245.3cm
A = length x breadth
= 25 x 20
= 500cm
20cm
A = 245.3cm2 + 500cm?
25cm
Your answer

From the figure given we know that the lower base measures 7+7 = 14 representing the distance between the point B and C

For the upper base the distance between the  point A and D is 5+3 = 8

The height can be founded from the distance between the point A and the lower base and we see that the hight is

Then the area can be founded with this formula:

And replacing we got:

Step-by-step explanation:

We can olve the problem with this way much easier.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
