## How to Calculate Area Of Pyramid

*Example: What is the area of pyramid with width = 18 units, length = 23 units and height = 50 units?*

As;

area of pyramid = width*length+length*√((width/2)^{2}+(height)^{2})+width*√((length/2)^{2}+(height)^{2})

By substituting the above given data in the previous function;

(i.e.) = 18*23+23*√((18/2)^{2}+(50)^{2})+18*√((23/2)^{2}+(50)^{2})

Answer is: units^{2}.
