A. 40 cm²

Penjelasan dengan langkah-langkah:

~ Luas trapesium

$\:$

Luas = ½ × (a + b) × t

Luas = ½ × (DE + FG) × DG

Luas = ½ × (8 + 12) × 4

Luas = ½ × 20 × 4

Luas = $\red{\underline{{\tt~40~cm²}}}$

Diketahui

DE = 8 cm

FG = 12 cm

EF = 5 cm

DG = 4 cm

Ditanya:

Luas Trapesium = ?

Dijawab:

› Trapesium Siku-siku

Luas Trapesium = ½ × ( Sisi a + Sisi b ) × t

$\sf \: L = \frac{1}{2} \times (a + b) \times t$

$\sf \: L = \frac{1}{2} \times (DE + FG) \times DG$

$\sf \: L = \frac{1}{2} \times (12 \: cm + 8 \: cm) \times 4 \: cm$

$\sf \: L = \frac{1}{2} \times (20 \: cm \times 4 \: cm)$

$\sf \: L = \frac{1}{2} \times 80 \: cm$

$\sf \: L = \frac{80 \: cm}{2}$

$\sf \: \green{\underline{{\tt~L = 40~cm²}}}$
