Answer:
d₂ = 15 cm
Step-by-step explanation:
The area (A) of a kite is calculated as
A = 
d₁d₂
Here A = 120, d₁ = 16 , then
× 16 × d₂ = 120
8d₂ = 120 ( divide both sides by 8 )
d₂ = 15 cm
ANSWER
A. (243pi+162) ft^2

The correct answer is A.
Answer:
C.) 5, 12, 13
Step-by-step explanation:
In a right triangle, the sum of the squares of the two shorter sides must equal the square of the longest side (Pythagoras).
a² + b² = c²
We can test each set of numbers to see which one fits.
A.) 8² + 12² = 16²
64 + 144 = 256
208 ≠ 256
B.) 6² + 7² = 8²
36 + 49 = 64
85 ≠ 64
C.) 5² + 12² = 13²
25 + 144 = 169
169 = 169
The numbers 5, 12, and 13 could represent the lengths of the sides of a right triangle.
D.) 16² + 32² = 36²
256 + 1024 = 1296
1280 ≠ 1296
Perimeter = 2L + 2W
42= 2L + 2(8)
26 = 2L
13 = L
