The lateral area for regular pyramid is given by:
A=l√((w/2)²+h²)+w√((l/2)²+h²)
where:
w=width
l=length
h=height
plugging the values in the formula we get:
A=6√((6/2)²+9²)+6√((6/2)²+9²)
A=6√90+6√90
A=12√90
A=113.842 sq. feet
A=

Answer:
Hey there!
The measure of angle ABD plus the measure of angle CBD equals 90 degrees or a right angle.
Thus, we can write the equation: ABD+51=90
Solving for ABD, we find that it is 39 degrees.
Let me know if this helps :)
