Tentukanlah keliling dan luas persegi panjang dengan panjang dan lebar: a. panjang = 1 m 20 cm lebar = 1 m 10 cm
b. panjang = 17 m 20 cm lebar = 1 m 30 cm
Makasih :)
5dregensleyerjawaban soal A kliling = 2 (p +l) = 2 (120 + 110) = 2 (230) = 460 cm luas = p x l = 120 x 110 = 13200 cm²
jawaban soal B klilig = 2 ( p+l) = 2 ( 1720 +130) = 2 (1850) = 3700 cm luas = p x l = 1720 x 130 = 223600 cm²

A. panjang = 120 cm lebar = 110 cm keliling = 2x(p+l) = 2x(120+110) = 2x240 =480 cm luas =pxl =120x110 =13.200 cm b. panjang =1720 cm lebar = 130 cm keliling = 2x(p+l) = 2x(1720+130) = 2x1850 = 3700 cm luas =pxl =1720x130 =223.600 cm maaf kalo salah
kliling = 2 (p +l)
= 2 (120 + 110)
= 2 (230)
= 460 cm
luas = p x l
= 120 x 110
= 13200 cm²
jawaban soal B
klilig = 2 ( p+l)
= 2 ( 1720 +130)
= 2 (1850)
= 3700 cm
luas = p x l
= 1720 x 130
= 223600 cm²
lebar = 110 cm
keliling = 2x(p+l)
= 2x(120+110)
= 2x240 =480 cm
luas =pxl =120x110 =13.200 cm
b. panjang =1720 cm
lebar = 130 cm
keliling = 2x(p+l)
= 2x(1720+130)
= 2x1850
= 3700 cm
luas =pxl =1720x130 =223.600 cm
maaf kalo salah
