Question

Ini gimana ya caranya?

Answer 1

Verified answer

8. wayan : putu = 4 : 9
Wayan = y
Wayan = 4/9 * 180.000 = 4 * 20.000
Wayan = D. Rp.80,000,00,-

9. K = (p+l) * 2
216/2 = 108 / ( 7 + 5 )
L = 108 / 12 = 9
P = 7 * 9 = 63
l = 5 * 9 = 45
L = 63 * 45 = D. 2835 cm²

Answer 2

8.uang wayan = 4/9 x 180000 = 80.000

9. kell=(2x(p+l))= (2x12l/5) maka l=45
dari perbandingan p:l=7:5 maka p=7l/5=7x45/5=63
luas=63x45=2835cm persegi
