Best ResponseYou've already chosen the best response.0I 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!

Best ResponseYou've already chosen the best response.2Find 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

Best ResponseYou've already chosen the best response.2No. Just take small steps. Can you find the area of the base (you know it is a square) with a side= 16

Best ResponseYou've already chosen the best response.2Can you find the perimeter of the base? 4* side = 4*16

Best ResponseYou've already chosen the best response.2The formula says Perimeter/2 so 64/2 = 32 *who ever is curious

Best ResponseYou've already chosen the best response.2Area = 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
