tolong di jawab ya di kumpulkan besok no 1-6 please banget yah

1) L gabungan
  = L 1/2 lingkaran + L persegi panjang + L segitiga
  = ( 1/2 x π x r² ) + ( p x l ) + ( 1/2 x a x t )
  = ( 1/2 x 22/7 x 7 cm x 7 cm ) + ( 20 cm x 14 cm ) + ( 1/2 x 10 cm x 14 cm )
  = 77 cm² + 280 cm² + 70 cm²
  = 427 cm²

3) Luas gabungan
  = L persegi panjang + L 1/2 lingkaran
  = ( p x l ) + ( 1/2 x π x r² )
  = ( 22 cm x 6 cm ) + ( 1/2 x 22/7 x 7 cm x 7 cm )
  = 132 cm² + 77 cm²
  = 209 cm²

4) Luas daerah yang diarsir
  = L persegi - L 1/2 lingkaran
  = ( s x s ) - ( 1/2 x π x r² )
  = ( 14 cm x 14 cm ) - ( 1/2 x 22/7 x 7 cm x 7 cm )
  = 196 cm² - 77 cm²
  = 119 cm²

5) Keliling gabungan
  = K persegi  + K panjang busur lingkaran
  = ( s x 3 ) + ( 1/2 x π x d )
  = ( 14 cm x 3 ) + ( 1/2 x 22/7 x 14 cm )
  = 42 cm + 22 cm
  = 64 cm

6) Luas gabungan
  = L persegi + L 1/2 lingkaran
  = ( s x s ) + ( 1/2 x π x r² )
  = ( 14 cm x 14 cm ) + ( 1/2 x 22/7 x 7 cm x 7 cm )
  = 196 cm² + 77 cm²
  = 273 cm²
