P=96 mm l=40 mm tentukan keliling dan luas

Luas = panjang x lebar
=96 mm x 40 mm
=3840mm²

Keliling = 2 x (p + l)
=2 x ( 96 + 40 )
=2 x 136
=272 mm

keliling = 2 x (p+l)
               2 × ( 96 mm + 40 mm)
               2 × 136 mm
               272 mm

Luas = p × l
             96 mm × 40 mm × 1mm²
            3840 mm²
