Dik:
Panjang Persegi Panjang = 25 cm
Lebar Persegi Panjang = 10 cm
Panjang sisi Trapesium
a. = 15 cm
b. = 25 cm
tinggi trapesium = 10 cm
Dit :
Luas Gabungan
Jawab:
L.persegi panjang = P × L
= 25 × 10 cm
= 250 cm²
L. trapesium = 1/2 × (a + b) × t
= 1/2 × (15 + 25) × 10 cm
= 1/2 × 40 × 10 cm
= 1/2 × 400
= 200 cm
Maka:
L. persegi panjang + L. trapesium
= 250 + 200 cm²
= 450 cm²
