Answer
probability of greater than 3 is 60%
not 5,6,7 or 8 is 60%
The area of a shape is the amount of space a shape can occupy, while the perimeter is the sum of its lengths.
- <em>The perimeter is </em>
<em>units</em> - <em>The area of the sanctuary is 27 square units</em>
We have:

<u>Perimeter</u>
See attachment for the layout of the sanctuary



From the attachment, the sides are
<em>AB, BF, FC, CD, DE and EA</em>
Start by calculating the length of each side using the following distance formula:

So, we have:






So, the perimeter (P) is:



<em>Hence, the perimeter is </em>
<em>units</em>
<u />
<u>Area</u>
To calculate the area, we need to divide the sanctuary into three.
- <em>Triangle ABF</em>
- <em>Triangle EFA</em>
- <em>Trapezium CDEF</em>
The area of ABF is:

Where:




The area of EFA is:

Where:


So:


The area of CDEF is:

Where



So, we have:



So, the area of the sanctuary is:




<em>Hence, the area of the sanctuary is 27 square units</em>

Answer:
b=2A/h-a
Step-by-step explanation:
A=1/2h(a+b)
a+b=A/(1/2h)
a+b=A/(h/2)
a+b=(A/1)(2/h)
a+b=2A/h
b=2A/h-a
