tolong dijawab cari luas , pakai caranya

Luas trapesium = 1/2.t(a+b)
= 1/2 . 18 (40 + 58)
= 9 (98)
= 882

Luas persegi = p.l
= 18 x 35
= 630

Total = 882 + 630
= 1.512 cm^2

Cara 1:
Ltotal = Ltrapesium + Ljajargenjang
= (1/2 × (35+53) × 18) + (40 × 18)
= 792 + 720
= 1.512 cm².

Cara 2:
Ltotal = Ltrapesium + Lpersegipanjang
= (1/2 × (22+40) × 18) + (53 × 18)
= 558 + 954
= 1.512 cm².

Cara 3:
Ltotal = Ltrapesium + Lpersegi panjang
= (1/2 × (40+58) × 18) + (35 × 18)
= 882 + 630
= 1.512 cm².

Semoga membantu...
