ANSWER

$7 {m}^(2)$

Step-by-step explanation

If the area of the circle is 84π m² , then the area of a 30° sector is just a proportion of the full circle.

The area of the 30° sector is

$(30)/(360) * 84\pi \: {m}^(2)$

$= (1)/(12) * 84 {m}^(2)$

$= 7 {m}^(2)$

Hence the area of the 30° sector of this circle is

$7 {m}^(2)$
