Answer:

B = 125 square mm,   P = 51 mm,  I = 15mm

Step-by-step explanation:

This looks like a equilateral pyramid.

So all the faces are equilaterals with side lengths  17 mm. ...

So  B = base area  =  125 square mm

P = perimeter = 17 + 17 + 17 = 51 mm

I = slant height = 15 mm.

verify B =   (1/2)* 17 * ( 17/2)*root(3) = 125.14  square mm
