length which can be measured using both the rods?
15 feet
0
9 feet
a. 6 feet
b.15 feet
c. 20 feet
d. 9 feet
(24)​

Answer 1

Answer:

45 feet

Step-by-step explanation:

length of Rod 1 = 9 feet

length of rod 2 = 15 feet

smallest length which can be measured by using both the rods = LCM of 9 and 15

LCM = 3×3×5 = 45 feet

There fore 45 feet is the smallest length which can be measured by both the rods

Answer 2

Answer:- Length of first rod= 9 feet

Length of second rod = 15 feet

Therefore, to find the smallest

length of both the rods we have to find the HCF of 9,15.

9 = 3×3

15 = 3×5

Common factor : 3

So, HCF = 3

Therefore, the smallest length which can be measured using both the rods is 3.
