Matematika tolong dijawab ya ,saya tidak mengerti​

tolong dijawab ya ,saya tidak mengerti​

Penjelasan dengan langkah-langkah:

1)

a = 5

t = 2,5

Luas = a/2 x t

Luas = 5/2 x 2,5

Luas = (2,5)²

Luas = 6,25 satuan luas

2)

a = 6

t = 3

Luas = a/2 x t

Luas = 6/2 x 3

Luas = (3)²

Luas = 9 satuan luas

3)

a = 6

t = 3

Luas = 6/2 x 3

Luas = 3 x 3

Luas = (3)²

Luas = 9 satuan luas
