Answer:

9 m²

Step-by-step explanation:

The area (A) of a sector of a circle is

A = area of circle × fraction of circle

  = 72 × [tex]\frac{45}{360}[/tex]

  = 72 × [tex]\frac{1}{8}[/tex] = 9 m²

it is 9 meters because 45÷360 is 0.125 and 0.125 as a fraction is 1/8. 72 ÷ 8 equals 9, therefore the answer is 9
