Correct option is B
Given:
The base of a right pyramid is a square.
Diagonal of the base = 16 unit.
slant edge =17
Formula Used:
a ,b and c are sides of right angle triangle where c is opposite to right angel.
a2 +b2= c2
Concept Used:
The point where the diagonals of square intersect each other is the midpoint of both the diagonals, effectively bisecting each other.
Solution:
In right angle triangle
perpendicular = vertical height
Hypotenuse= slant edge =17
base = half of diagonal
So, according to right angle triangle
172 =82 +( vertical height )2
289-64 =( vertical height )2
vertical height = 15
