The net of a square pyramid is show: what is the surface area of the figure? 20 points answer

  0.6625 square inch

Step-by-step explanation:

The area of the central square in square inches is

  area = s²

     = 0.25² = 0.0625.

The area of each triangular side is ...

  area = 1/2bh

     = 1/2·0.25·1.2 = 0.15

So, the sum of the areas of the four sides and the base is ...

  4(0.15) +0.0625 = 0.6625 . . . . square inches

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
