    I suggest going through your notes and figuring out what slant height is. Or searching on the internet somewhere. It's been my experience that trying to work out a maths problem when I don't know what the words mean is very hard!

    The formula you are looking for is 2bs+b^2

    Find the area of the base (the bottom) which is a square 16*16 find the area of the sides. this is Perimeter of the base/2 times slant height Perimeter is 4 times the base side= 4*16= 64 64/2= 32 so 32*17 for the sides

    No. Just take small steps. Can you find the area of the base (you know it is a square) with a side= 16

    Can you find the perimeter of the base? 4* side = 4*16

    The formula says Perimeter/2 so 64/2 = 32 *who ever is curious

    Area = Base area + P*S/2 where we already figured out Base area= 256 P is perimeter , we got 4*16= 64 P/2 =32 S is given as 17 so Area = 256 + 32*17 = 800

    It is no harder than following a recipe to cook a meal (actually easier, because you can't hurt yourself when dicing up the food)

    It looks fine. The important thing is (1) remember it (2) be able to use it.

    Thanks for the intriguing method, it is easier to understand if your not into geometry
