tolong jawab pake caranya pliss

L. Jajargenjang = a x t
= 17 x 12
= 204 cm

L. Trapesium = (a+b) x t/2
= (25+17) x 10/2
= (42) x 5
= 210 cm

Total = 204 + 210 = 414 cm^2

Luas trapesium
= 1/2 (25 + 17) X 10
= 42 X 5 = 210
Luas jajargenjang
= 17 X 12
= 204
Luas gabungan = 210 + 204
= 414 cm persegi
