Sehemu B — Ufumbuzi na kazi (Maswali 41–45)

Q41. Eneo la parallelogram = base × height = 18 cm × 10 cm = 180 cm².
```
Kazi: A = b × h = 18 × 10 = 180 cm²
```
Q42. Mama alipika 120. Alitoa 1/3 kwa majirani ⇒ 1/3×120 = 40. Iliyobaki = 120 − 40 = 80. Imegawanywa kwa ratio 1:2 ⇒ total parts = 3. Mwana A = 1/3×80 = 26.666... hata hivyo tunatumia intimation: 80×1/3 = 26 2/3 ≈ 26 2/3; Mwana B = 2/3×80 = 53 1/3 ≈ 53 1/3.
```
Kazi na jibu (kwa nambari kamili): Kama vitu vinavyogawanywa ni 80 na mgawanyo 1:2, sehemu = 3 parts. Mwana A = 80×1/3 = 26 2/3, Mwana B = 80×2/3 = 53 1/3. (Ikihitajika vitu kamili, binu upunguze kikapu mpaka kutoshe.)
```
Q43. Bei ya simu = 120,000 TSh. Upunguzo 15% = 0.15×120,000 = 18,000. Bei mpya = 120,000 − 18,000 = 102,000 TSh.
```
Kazi: 15% of 120000 = 0.15×120000 = 18000. New price = 120000−18000 = 102000 TSh
```

Q44. Eneo la mviringo = π r². Kwa r = 14, π = 22/7.

A = (22/7)×14² = (22/7)×196 = 22×28 = 616 cm². Jibu: 616 cm².

Q45. Wastani = 79 kwa wanafunzi 5. Jumla = 79×5 = 395. Sasa jumla ya alama nyingine = 72+65+80+90 = 307. x = 395 − 307 = 88.
```
Kazi: 79×5 = 395; 395 − (72+65+80+90) = 395 − 307 = 88.
```

Kumbuka: Q42 ilitoa sehemu zisizo kamili; unaweza kupendekeza utiifu wa jinsi vitu hela - kama vitu ni kamili au vinagawanywa vibakan vitendo vinategemea muktadha. Kwa ajili ya mitihani ya kitaifa wajibu ni kuonyesha kazi na kuwa sahihi kwa miseupo uliotolewa.

Karatasi hii imeandaliwa kwa MUUNDO unaofuata sera za PSLE/NECTA (sehemu A na B — idadi ya maswali = 45). Taarifa ya muundo imethibitishwa kwa nyaraka rasmi za NECTA/PSLE na vitabu vya mitaala ya Standard Seven. :contentReference[oaicite:1]{index=1}
