panjang taman = 7x
lebar = 4x
k = 2p + 2l (jumlah smua sisi)
= 286 = 2(7x) + 2(4x)
= 14x + 8x
= 22x
x = 13
panjang = 7x = 7(13)
= 91m
lebar = 4x = 4(13)
= 52m
diketahui perbandingan panjang dan lebar sebiah taman 7 : 4
Keliling taman 286 cm
Jawab :
p : l = 7 : 4
p = 7/4 l
Keliling = 286
2 (p + l) = 286
2(7/4 l + l) = 286
7/4 l + 4/4 l = 143 ---> kedua ruas dibagi 2
11/4 l = 143
11 l = 572
l = 572/11 = 52 cm
p = 7/4 l = 7/4 x 52 = 91 cm
Jadi panjang taman 91 cm dan lebarnya 52 cm
