Tolong diisi dong plus di bawa besok

CB² = AB² + AC²
CB² = 36² + 27²
CB² = 1,296 + 729
CB² = 2,025
CB = √2,025
CB = 45 Cm

Keliling Segitiga
= Jumlah Seluruh Sisi
= 27 + 36 + 45
= 108 Cm


03.
1 cm di denah mewakili 1,500 Cm
Maka,
a = 9 x 1,500 = 13,500Cm = 135M
b = 4 x 1,500 = 6,000Cm = 60M
T = 6 x 1,500 = 9,000Cm = 90M

Luas Trapesium
= ½ x (a + b) x T
= ½ x (135 + 60) x 90
= ½ x 195 x 90
= 8,775 M2


04.
Luas Selimut Tabung
= π x d x T
= 22/7 x 21 x 29
= 1,914 Cm²


Maaf kalau benar ya kak...
Let's math every^DAMN^day!

2. Sisi miring segitiga =v/27^2+36^2 =45

Keliling = s+s+s=27+36+45=108

3. Luas tanah = (4*1500+9*1500)*6*1500/2
=(6000+13500)*4500
=87750000cm^2
=8775m^2

4. Luas selimut = keliling*t=22/7*21*29=1914cm^2
