Jawaban:

D. 2500

Penjelasan dengan langkah-langkah:

menentukan tinggi pada sisi tegak atap

= √3² + (1/2(8))²

= √3² + 4²

= √9 + 16

= √25

= 5 m

L 4 sisi atap

= 4 L ∆

= 4 (1/2 x 8 m x 5 m)

= 4 x 20 m²

= 100 m²

banyak genting

= 100 m² x 25buah

= 2500 buah

Answer 2

TSTA :

= √3² + (1/2 × 8)²

= √(3(3) + (1(8/2)²

= √9 + 4²

= √9 + (4(4)

= √9 + 16

= √25

= √(5(5)

= √5²

= 5 M

LP :

= 4L

= 4(1/2(8(5)

= 4(1/2(40)

= 4(1(40/2)

= 4(20)

= 80 M²

TOTAL / BANYAKNYA GENTING :

= (80(25)

= 2.000 GENTING (C)
