a.114 cm2. (p×l)
b.295,2 cm2 (p×l)
c.6 cm (luas÷p)
d.22,5 m. (luas÷p)
e.15 dm. (luas÷p)
maaf cuma no 1 aja
maaf juga kalau salah
L = p x l
a.) p = 12 cm; l = 9,5 cm
L = 12 cm x 9,5 cm = 114 cm²
c.) p = 38 cm; L = 228 cm²
l = 228 cm² : 38 cm = 6 cm
d.) l = 13,8 m; L = 310,5 m²
p = 310,5 m² : 13,8 m = 22,5 m
BUJUR SANGKAR
L = s x s
1.) s = 23,6 cm
L = 23,6 cm x 23,6 cm = 556,96 cm²
3.) L = 144 cm²
s = √144 cm² = 12 cm
JAJARAN GENJANG
L = a x t
1.) a = 45 cm; t = 12 cm
L = 45 cm x 12 cm = 540 cm²
2.) t = 13 cm; L = 234 cm²
a = 234 cm² : 13 cm = 18 cm
3.) a = 35 cm; L = 490 cm²
t = 490 cm² : 35 cm = 14 cm
SEGITIGA
L = ½ x a x t
1.) a = 46 dm; t = 12 dm
L = ½ x 46 dm x 12 dm = 276 dm²
3.) t = 14 cm; L = 196 cm²
a = 196 cm² : ½ x 14 cm = 28 cm
4.) a = 46 m; L = 552 m²
t = 552 m² : ½ x 46 m = 24 m
Maaf ya kalo ada yang salah
Semoga membantu
