Step-by-step explanation:
Area of sector = 324 cm2
rl / 2 = 324
Multiply each side by 2.
rl = 648
Substitute 27 for r.
27l = 648
Divide each side by 27.
l = 24 cm
Perimeter of sector is
= l + 2r
= 24 + 2(27)
= 24 + 54
= 78 cm

Answer:
Area of sector = 324 cm2
rl/2 = 324 cm
multiply each side by 2
substitude 27 for r.
271 = 686
Divede each side by 27
1 = 24 cm
perimeter of sector is
= 1 + 2 r
= 24+2(27)
= 24+54
= 75 cm.
