toling bantuan nya nomer 29..........dgn cara nya

1/2d2 = √13^2 - (1/2 . 24)^2
1/2d2 = √169 - 12^2
1/2d2 = √169 - 144
1/2d2 = √25
1/2d2 = 5cm
d2 = 5 × 2
d2 = 10cm

Luas permukaan =
2( luas alas) + tinggi ( keliling alas) =
2 ( 24 × 10 / 2) + 20 ( 13 × 4) =
2( 120) + 20(52) =
240 + 1040 =
1280cm^2 ( D )

Kalau boleh jadikan jawaban terbaik yab.

LP=2L alas+K×t
    =2(d₁×d₂/2)+(4s)×20cm
    =2((24cm)/2×(2(√(s)²-(1/2d₁)²)))+(4(13cm))×20cm
    =2(12cm×(2(√(13cm)²-(1/2(24cm))²)))+52cm×20cm
    =2(12cm×(2(√169cm²-(12cm)²)))+1040cm²
    =2(12cm×(2(√169cm²-144cm²)))+1040cm²
    =2(12cm×(2(√25cm²)))+1040cm²
    =2(12cm×(2(5cm)))+1040cm²
    =2(12cm×10cm)+1040cm²
    =2(120cm²)+1040cm²
    =240cm²+1040cm²
    =1280cm²
