Answer:

21.99 units

164.93 units²

Step-by-step explanation:

given radius r = 15 units

angle of sector = 84°

Length of sector = $\frac{84}{360}$ x 2 x π x r

= $\frac{84}{360}$ x 2 x 3.14 x 15

= 21.99 units

Area of sector = $\frac{84}{360}$ x π x r²

= $\frac{84}{360}$ x 3.14 x 15²

= 164.93 units²
