Question

Jika skala denah adalah 1 : 250 maka luas meja adalah..........m


kak tolong bantu jawab +cara buat besokkk ....

Answer 1

Verified answer

Skala = 1 : 250

Diameter meja pada denah = 2 cm
Diameter meja sebenarnya = Diameter meja pada denah : skala
                                            = 2 cm : 1/250
                                            = 2 cm x 250
                                            = 500 cm
                                            = 5 m

Luas Meja
D = 5 m
r = D/2 = 5m / 2 = 2,5 m

L = π.r²
L = 3,14 x (2,5 m)²
L = 3,14 x 6,25 m²
L = 19,625 m²
