Answer 2

Aria totala =Aria bazei +Aria laterala

Abazei=l²=-6²=36 unitai patrate, ca nu ne-ai zis de care anume

Alaterala =Perimetrulbazei*Apotema piramidei/2

Perim.bazei =4*6

apotema piramidei= (Pitagora)=√(inaltime²+apotema bazei²)=√(9²+(6/2)²)=

√(9²+3²)=3√10

aria laterala=4*6*3√10/2=2*6*3√10=36√10 unitati patrate

Aria totala=36+36√10=36(1+√10) unitați patrate
