Answer:
c
Step-by-step explanation:
structure with a square or triangular base and sloping sides that meet in a point at the top
3.2
0 = 2t - 8/5
8/5 = 2t
16/5 = t
3.2 = t
L = 15, W = 8
Perimeter = 2(L + W)
P = 40
L = 2W - 1
40 = 2((2W-1) + W)
40 = 4W - 2 + 2W
40 = 6W - 2
42 = 6W
W = 8
Since L = 2W - 1
L = 2(8) - 1
L = 15
