Answer:
161.5 in.^2
Explanation:
Since you don't have a figure, from your description, I understand that the base of each small upper triangle is 8.5 inches. That means that each small triangle on top has a base of 8.5 inches and a height of 5 inches, and each small triangle below has a base of 8.5 inches and a height of 13 inches. My calculations below are base don this understanding.
The area of a kite is
A = (Bb)/2
where B and b are the lengths of the diagonals.
The diagonals have lengths:
B = 13 in. + 6 in. = 19 in.
b = 8.5 in. + 8.5 in. = 17 in.
A = (Bb)/2
A = (19 in. * 17 in.)/2
A = (323 in.^2)/2
A = 161.5 in.^2
