[tex]T.S.A=A+\text{ }\frac{1}{2}ps[/tex]

where A is the area of base

P is the perimeter of base

s is the slant height

From the diagram given,

Area of the base which is the area of the square is given by

A= 5 x 5 = 25 cm²

Area of the four triangles is given by

[tex]Area\text{ of the 4 triangles = }\frac{1}{2}\times5\times8\times4[/tex]

[tex]=80cm^2[/tex]

[tex]T\mathrm{}S\mathrm{}A=25+80=105cm^2[/tex]
