Jawab:
Lp =165 cm²
Penjelasan dengan langkah-langkah:
t trapesium =12-7 =5 cm
L = L pp+ L trapesium
=pxl + 1/2 (a+b) t
= 15 x 7 + 1/2 (15+9) x 5
=105 + 60
=165 cm²
L persegi
= p×l
=15×7
=105 cm
Ltrapesium
=[(a+b)×t]:2
=[(15+9)×5]:2
=(24×5):2
=120:2
=60 cm²
Jadi luas persegi panjang+trapesium
=105cm²+60 cm =165cm²
