[tex]7m[/tex]
Explicación paso a paso:
Area lateral: [tex]A_{L} = 420m^{2}[/tex]
Perímetro de la base : [tex]P_{b} = 120m[/tex]
Apotema de la pirámide: [tex]a_{p} = ?[/tex]
Fórmula:
[tex]A_{L} = \frac{P_{b} * a_{p} }{2}[/tex]
[tex]420m^{2} = \frac{120m*a_{p} }{2}[/tex]
[tex]2(420m^{2}) = 120m * a_{p}[/tex]
[tex]840m^{2} = 120m* a_{p}[/tex]
[tex]\frac{840m^{2} }{120m} = a_{p}[/tex]
[tex]7m = a_{p}[/tex]
[tex]a_{p} = 7m[/tex]
RESPUESTA:
