23) C. Limas Segi empat 24) L = 1/2 × (jumlah sisi sejajar) × t = 1/2 × (26 + 20) × 12 = 1/2 × 46 × 12 = 276 cm² 25) L persegi panjang : = p × l = 20 × 7 = 140 L segitiga : = 1/2 × a × t = 1/2 × 5 × 10 = 25 cm L total 140 + 25 = 165 cm²
26) 1/2 × π × r² = 1/2 × 22/7 × 14 × 14 = 308 cm² 27) v = p × l × t = 18 × 9 × 6 = 972 cm²

23. A 24. - 25. L.persegi panjang = p xl = 7 x 20 = 120
L. segitiga = 1/2 x alas x tinggi = 1/2 x 5 x (7 + 3) = 1/2 x 5 x 10 = 5 x 5 = 25
24) L = 1/2 × (jumlah sisi sejajar) × t
= 1/2 × (26 + 20) × 12
= 1/2 × 46 × 12
= 276 cm²
25) L persegi panjang :
= p × l
= 20 × 7
= 140
L segitiga :
= 1/2 × a × t
= 1/2 × 5 × 10
= 25 cm
L total
140 + 25 = 165 cm²
26) 1/2 × π × r²
= 1/2 × 22/7 × 14 × 14
= 308 cm²
27) v = p × l × t
= 18 × 9 × 6
= 972 cm²
24. -
25. L.persegi panjang = p xl
= 7 x 20 = 120
L. segitiga = 1/2 x alas x tinggi
= 1/2 x 5 x (7 + 3)
= 1/2 x 5 x 10
= 5 x 5 = 25
jumlah 120 + 25 = 165
26. L = 1/2 x r^2
1/2 x 22/7 x 14 x 14 = 308
27. V. balok = p xl x t
= 9 x 6 x 18
= 972
