Geometry 100 points fast i need this no so badly hlep

The area of the base is n(base*apotheme)/2 (actually the sum of the 5 subdivided triangles).  Surface area is the sum of the lateral surface area + area of the base.   Apothem is the distance between the centre of the pyramid base and the mid-point of any side (6.2 in this case).     ?? n=5 for a polygon of 5 sides.

entering that problem on the tube might get you an answer

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
