Answer:

301.6cm^2

Explanation:

3x+2x+x+90°=360(sum of shoes in circle equals 360°)

6x+90=360

6x=360-90

6x=270

divide both sides by 6

6x/6=270/6

x=45°

therefore 3x=3*45

=135

Area of the shaded sector

area of a sector =β(tita) /360*πr^2

=3x/360*πr^2

=3*45/360*πr^2

135/360*πr^2

Let π be 22/7

note r=16

0.375*22/7*(16)^2

0.375*22/7*256

0.375*3.143*256

ANS=301.728

The measurement closest is 301.6cm^2
