A building in san fransico is shaped like a square pyramid. It has a slant height of 856.1 feet and each side of its base is 145 feet long. Find the lateral area of the building.
A=l√[(w/2)²+h²+w]+w√[(l/2)²+h²] where l is base length w base width h is height
given that the slant side of our pyramid is 856.1 ft with square base of 145 ft, the height of the pyramid will be found by Pythagorean theorem. c²=a²+b² hence: 856.1²=a²+72.5² a=853.025 ft The Lateral area is therefore going to be: A=145√[(145/2)²+856.025²+145]+145√[(145/2)²+856.025²] A=249,136.0025 ft²
