Answer
Option A is correct.
Step-by-step explanation
The right answer will have the ratio of corresponding sides being constant all through.
32 ft, 16 ft and 24 ft.
Option A
4 ft, 2 ft, 3 ft
(32/4) = 8
(16/2) = 8
(24/3) = 8
Since 8 = 8 = 8, the side lengths in this option could belong to a dilation of the triangle JKL.
Option B
8ft, 4 ft, 7ft
(32/8) = 4
(16/4) = 4
(24/7) = 3.43
4 = 4 ≠ 3.43
The side lengths in this option cannot belong to a dilation of the triangle JKL.
Option C
40 ft, 24 ft, 32 ft.
(32/40) = (4/5)
(16/24) = (2/3)
(24/32) = (3/4)
(4/5) ≠ (2/3) ≠ (3/4)
The side lengths in this option cannot belong to a dilation of the triangle JKL.
Option D
64 ft, 34 ft, 48 ft
(32/64) = (1/2)
(16/34) = (8/17)
(24/48) = (1/2)
(1/2) ≠ (8/17) ≠ (1/2)
The side lengths in this option cannot belong to a dilation of the triangle JKL.
Hope this Helps!!!
