Question

Tolong yaa no 23 pakai cara

Answer 1

L1 = 1/2 x a x t
     = 1/2 x 14 cm x 18 cm
     = 126 cm²

L2 = 1/2 x t ( a + b )
     = 1/2 x 16 cm (18 cm + 30 cm)
     = 8 cm x 48 cm
     = 384 cm²

Luas gabungan = 126 cm² + 384 cm²
                          = 510 cm² (B)

Answer 2

L1= 1\2 ×t
=1\2 ×14cm× 18cm
=126cm²

l2=1\2×t (a+b)
=1\2 ×16 cm ( 18 cm + 30 cm )
= 8cm × 48cm
= 384 cm²

luas gabungan=126cm² + 384cm²
=510cm²(b)
