  A. panjang sisi = √900
  = 30
  b. keliling = 4×30
  keliling = 120
  c. diagonal = ✓30²+30²
  = √900+900
  = √1800
  = √900×2
  =30√2

  A.
  Lpersegi²=900cm²
  s²=900cm²
  s=√900cm²
  s=30cm
  b.
  Kpersegi=4s
                 =4(30)
                 =120cm

  Matematika SMP Kelas VIII
  
  a] ∠BCD = 90° + 45° = 135°
  
  b] ∠BCE = 90° - 45° = 45°
  
  c] EB = 20 - 15 = 5 cm
  
  d] karena segitiga siku-siku sama kaki, maka
  CE = EB = 5 cm
  
  e] BC = 2√CE = 2√5 cm
  
  f] AC = √(AE² + CE²)
  AC = √(15² + 5²)
  AC = √(225 + 25)
  AC = √250
  AC = 5√10
  
  g] BD = √(AD² + AB²)
  BD = √(5² + 20²)
  BD = √(25 + 400)
  BD = 5√17 cm
  
  h] keliling = AB + BC + CD + DA
  keliling = 20 + 2√5 + 15 + 5
  keliling = (40 + 2√5) cm
  
  i] luas = 1/2 x t x jumlah sisi
  luas = 1/2 x 5 x (20 + 15)
  luas = 87,5 cm²
