Penjelasan dengan langkah-langkah:

1)

persegi panjang

keliling = 2 (p+ L)

26 = 2 (p + 6)

26 = 2p + 12

2p = 26 - 12

2p = 14

p= 7 m

luas = panjang x lebar = 7 x 6 = 42 m² = 420000 cm²

luas ubin = 40 x 30 cm = 1200 cm²

banyaknya ubin = (420000/1200) x 1 ubin = 350 ubin

2)

keliling jajar genjang = 2 x (13 + 12) = 50 cm

(50 : 2,5) x 1 pohon palem = 20 pohon palem

3)

keliling persegi = 4 x sisi

40 = 4s

sisi = 10 m

luas persegi = sisi² = 10² = 100 m²

luas belah ketupat = ½ x d1 x d2 = ½ x 10 x 10 = 50 m²

luas sisa = 100 - 50 = 50 m²

harga rumput = 50 x 50.000 = Rp 2.500.000,00

4) (buat gambar sendiri ya)

dalam ukuran persentase :

pramuka = (11/40) x 100% = 27,5%

KSPAN = (9/10) x 100% = 22,5 %

volley = (5/40) x 100% = 12,5 %

basket = (4/40) x 100% = 10%

PMR = (8/40) x 100% = 20%

futsal = (3/40) x 100% = 7,5%

dalam ukuran derajat :

pramuka = (11/40) x 360° = 99°

KSPAN = (9/40) x 360° = 81°

volley = (5/40) x 360° = 45°

basket = (4/40) x 360° = 36°

PMR = (8/40) x 360° = 72°

futsal = (3/40) x 360° = 27°
