A pendulum that swings fully once in 1.9 seconds has a length of 2.93 feet.
<h3>What is the length of a pendulum?</h3>
A basic pendulum is a machine in which the point mass is hung from a fixed support by a light, inextensible string.
Length of pendulum is defined as the distance between the point of suspension to the center of the bob and is denoted by " 1 ".
Given the equation:
where L is the length in feet and T is the time in seconds.
Given that T = 1.9sec,
Hence:
L = 2.93 feet
A pendulum that swings fully once in 1.9 sec has a length of 2.93 feet.

Answer:
9 and 11
Step-by-step explanation:
Perimeter= 2w+2l
l=w+5
Substitute for l
p= 2w+2(w+5)
p= 2w+2w+10
p= 4w+10
58=4w+10
48=4w
12= w
Plug in the width to find length.
l= 12+5
l=17
Final answer: Length-17 cm, Width-12 cm
