Answer 1

Verified answer

23) jawab A

25)
luas ½ lingkaran
L = ½πr²
L = ½ x 22/7 x 14²
L = ½ x 22/7 x 196
L = ½ x 616
L = 308 cm²

luas trapesium
L = ½(a+b)t
L = ½ x (28 + 48) x (30 - 14)
L = ½ x 76 x 16
L = 608 cm²

luas total
308 + 608 = 916 cm²

Answer 2

23. limas segitiga
25.


bngun 1 = r = 14
= 1/2 22/7 x 14 pgkt 2
= 1/2 x 22/7 x 196
= 1/2 x 22 x 28
= 308

30 - 14 = 16

bngun 2 = (28 + 48) x 16 / 2
= 76 x 16 / 2
= 608

jd 608 + 308 = 916
