Hello, can you help me? “answered with an explanation” Thanks You.
L = L persegi panjang + L segitiga
L persegi panjang
= p × l
= 15 cm × 10 cm
= 150 cm²
L segitiga
Cari dulu tingginya
a² + b² = c²
9² + t² = 15²
81 + t² = 225
t² = 225 – 81
t² = 144
t = √144 = 12 cm
L segitiga = ½ × a × t
= ½ × 9 cm × 12 cm
= 9 cm × 6 cm
= 54 cm²
L = 150 cm² + 54 cm²
L = 204 cm²
( tidak ada opsi yang tepat)
240 cm² (Tidak Ada Di Opsi)
