Well anyways. With the info we have, we can put it into the formula \[\huge (a^{2})+(4*\frac{1}{2}*sh*a)\] with a being the side of the square and sh being the slant height

You there?

10 for the area and 12 for the slant height

i am dummy its 100
anonymous
  • anonymous
Ok yeah, 100. So \[\large 4*\frac{1}{2}*12*10=~?\]
anonymous
  • anonymous
240 + 100 = 340
anonymous
  • anonymous
Right! So 340 is gonna be our answer :)
