L = 28 1/2 m²
lebar = 4 3/4 m

L = panjang x lebar
28 1/2 = p x 4 3/4
57/2 = p x 19/4
p = 57/2 : 19/4
p = 57/2 x 4/19
p = (57 : 19) x (4 : 2)
p = 3 x 2
p = 6 m

Keliling = 2(p + l)
             = 2(6 + 4 3/4)
             = 2 x 10 3/4
             = 2 x 43/4
             = 86/4
             = 21 2/4
             = 21 1/2 m
