Answer:
The length of pendulum is 55.853cm
Step-by-step explanation:
We are given
the original pendulum completed one swing every 1.5 seconds
so, T=1.5 sec
now, we can use time period formula

l is the length of pendulum
g is acceleration due to gravity

now, we can plug values
and then we can solve for l



In cm

Parallelogram so
CD = AB
18x - 5 = 15x + 4
3x = 9
x = 3
answer
x = 3
