Answer: 21.6 m

Step-by-step explanation:

Given

A football field measures $100\ m\times 72\ m$

If a football field similar in shape to a full size has a length $l=30\ m$

The ratio of the length of the original to the small field is the same

Assume the width of the small field is w

$\therefore \dfrac{100}{30}=\dfrac{72}{w}\\\\\Rightarrow w=30\times \dfrac{72}{100}\\\\\Rightarrow w=21.6\ m$

Thus, the width of the field is 21.6 m
