Okay. fist off don't think of them as 5 units each, but 1. so if you were to put it on graphing paper and box squares each time. you would be able to get 8 in for both sides to make a square. Area then would be 1600ft squared because 8 ×5 is 40 and 40×40 is 1600. then you calculate how many squares you used. 8×8=64. and 80-64=16 so 16 pieces are left over. then 9×9 (increasing the square) is 81. so 17 pieces to increase it.
By a Challenge that way It’ll be even
The answers that apply are Triangles, Squares, and Rectangles. Because when you look at the base of the pyramid more closely, they are maded of 3 different kinds of shapes.
It is 546.4583333333333, which would simplify to 546.46 if to the hundredths place or 546.5 to the tens place
