Luas segitiga
(1/2 × a × t)
= 1/2 × 8 × 18
= 8 × 9
= 72

luas trapesium
(1/2 ×(a + b) × t)
= 1/2 ×(18 + 14) × 8
= 1/2 × 32 × 8
= 32 × 4
= 128

luas gabungan
= 72 + 128
= 200 cm² ( a )

L trapesium =

$frac{(a + b) times t}{2}$

(14+18)×8/2

32×4=128cm²

L segitiga siku siku =

a×t/2

8×18/2=72cm²

128+72=200cm²
