Tolong jawab ya no 4 & 5

4. Persegi panjang -> 15m × 22m
Harga per meter^2 = Rp 300.000
Harga?
Jb. Harga = 15×22 m^2× Rp 300.000
Rp 99.000.000

5.
AB = 24 cm
BD = 26 cm
K segitiga DCB?

AD^2 = BD^2 - AB^2
AD^2 = (26)^2 - (24)^2
AD^2 = 676-576
AD^2 = 100
AD = 10 cm

AD = BC = 10 cm
AB = DC = 24 cm

K= DC + BC + DB
K= (24 + 10 + 26) cm
K= 60 cm

4. L tanah = p x l
= 22 x 15
= 330 m²
harga 1 m² = Rp. 300.000 x 330 m² = Rp.
99.000.000

5. L = p x l
240 = 24 x l
240 : 24 = l
10cm = l

K = 10+ 26+ 24
= 60cm
