directrix · Answer

The Lateral Area of a regular pyramid can be found by taking 1/2 the perimeter of the square base multiplied by the slant height.

LA = (1/2)* (4*60) * 40 where 4*60 is the perimeter of the square base and 40 is the slant height. This should crank out to be 4,800 square meters. Check and see.
