lebar = x
panjang = 2x
keliling = 2(p+l)
66 cm = 2 (2x+x)
66 : 2 = 3x
33 = 3x
11 = x
a. panjang = 2x =2(11) = 22
lebar = x =11
b. Luas = p x l = 22 x 11 = 242 cm²
jawaban:
A). p = 2l
K = 2(p+l)
K = 2(2l + l)
66 = 2(2l + l)
66 = 2(3l)
66 = 6l
l = 66/6
l = 11 cm
p = 2l
p = 2(11)
p = 22 cm
B). Luas Persegi Panjang
=> p × l
=> 22 × 11
=> 242 cm²
