10. Which of the following could be the lengths of the three sides of a triangle? A 1 cm, 2 cm, 3 cm
B. 3 in., 3 in., 7 in.
C. 4ft, 8 ft, 12 ft
D. 5 cm, 7 cm, 9 cm

B is the correct answer

Step-by-step explanation:

D

Step-by-step explanation:

the sum of any two sides of a triangle must be greater than the third side.

5 + 7 = 12

12 > 9

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

21/58.
