tolong bantu jwb 1 s/d 3

1. Keliling persegi = 4 x s
                             = 4 x 19
                             = 76 cm²

2. Keliling persegi panjang = 2 x ( p +l)
                                           = 2 x ( 17 + 8)
                                           = 50 cm²

3. Luas persegi panjang = p x l
                                       = 15 x 8
                                       = 120 cm²

1. Keliling persegi =
4 x s =
4 x 19 =
76 cm²

2. Keliling persegi panjang =
= 2 x ( p +l)
= 2 x ( 17 + 8)
= 2 x 25
= 50 cm²

3. Luas persegi panjang
= p x l
= 15 x 8
= 120 cm²

Kalau boleh jadikan jawaban terbaik yab
