luas segitiga = (alas X tinggi)
= (20 X 12) *tinggi didapat dari pytaghoras
= (240)
= 120
luas persegi panjang = panjang X lebar
= 15 X 16
= 240 cm^{2} [/tex]
luas-nya = 120 + 240
= 360 cm^{2} [/tex]
= √(13² - 12²)
= √(169 - 144)
= √25
= 5 cm
Luas segitiga
= 1/2 . a . t
= 1/2 . 24 . 5
= 60 cm²
Luas Persegi Panjang
= p x l
= 16 x 15
= 240 cm²
Luas total = 60 + 240 = 300 cm² (B)
