Jawaban
Keliling = 2 × (P + L)
90 = 2 × (24 + L)
90 = ( 2 × 24 ) + ( 2 × L )
90 = 48 + 2 × L
90 - 48 = 2 × L
42 = 2 × L
42 : 2 = L
21 = L
L = 21 cm ( C )
Jawaban:
Keliling persegi = 90cm
Panjang persegi = 24cm
Berapakah lebarnya?
Keliling = 2 ( p + l )
90 = 2 ( 24 + l)
90 = 48 + 2l
2l = 90 - 48
2l = 42
l = 42 ÷ 2
= 21 cm
