To solve this, we are ggoing to use the formula below:


T.S.A=A+\text{ }(1)/(2)ps

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


Area\text{ of the 4 triangles = }(1)/(2)*5*8*4


=80cm^2


T\mathrm{}S\mathrm{}A=25+80=105cm^2
