Answer:
Density is nearly 3 cabs per hectare
Explanation:
Given -
There are three three intertidal regions.
Area of each intertidal region is 
hectares.
Number of crab in the intertidal regions are as follows -
Intertidal region I - 7
Intertidal region I - 2
Intertidal region I - 6
Sum of crabs in all three regions is equal to
Total area of all three intertidal regions is equal to
hectares
Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions
Density 
Density is nearly 3 cabs per hectare
The Brodmann areas are a method of mapping the cortex and its distinct functions that was developed by Korbinian Brodmann, after whom the areas are named.
Korbinian Brodmann (November 17, 1868 – August 22, 1918) was a German neurologist best known for classifying the cerebral cortex into 52 distinct regions based on cytoarchitectonic (histological) characteristics. These areas are now commonly known as Brodmann areas.
The Brodmann classification divides the cortex into approximately 52 sequentially numbered areas, though some regions have since been subdivided and others are only found in non-human primates.
It is in charge of motor movements such as contralateral finger/hand/wrist or orofacial movements, learned motor sequences, breathing control, and voluntary blinking. The primary visual cortex (Brodmann area 17) is located on the medial surface of the occipital lobe, in and on either side of the calcarine sulcus.
