Answer:
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.\sf{\huge{\underline{\orange{Given :-}}}}

Solution:−
Let the legth be in form of x,
The parallel sides of a trapezium are in the ratio 3 : 4.
Such that, 3x & 4x
The height is 9 dm
We know that the area of triangle,
➝ ½ × sum of || sides × height
➝ ½ × (3x + 4x) × 9 ------(1)
The area of given trapezium is 126 dm².------(2)
From Equation. 1 & 2
½ × (3x + 4x) × 9 = 126
➝ ½ × 7x × 9 = 126
➝ 7x = 126 × 2/9
➝ 7x = 252 /9
➝ 7x = 28
➝ x = 28/7
➝ x = 4
The sides become 3x = 3 × 4 = 12 & 4x = 4 × 4 = 16.
The lengths of smallest parallel side is 12 dm .
