Verified answer

5.) Luas Trapesium ABCD

= ½(a+b)t

= ½ x (26 + 13) x 16

= 39 x 8

= 312 cm²

6.) Luas daerah berbayang

Luas 4 ¼ lingkaran = 1 lingkaran

Luas lingkaran

=

= x 7 x 7

= 22 x 7

= 154 cm²

Luas persegi

= s²

= 21²

= 441 cm²

Luas daerah berbayang

= 441 cm² - 154 cm²

= 287 cm²
