Tolong dijawab pakai caranya

1. L=pxl
      =80x80
      = 6.400
2. S=L:4
       =2.500:4
       =625cm
3. L=1/2xaxt atau axt/2
      =60x40/2
      =2.400/2
      =1.200cm
4. L=alasxtinggi
      =10x8
      =80cm2
5. L=DxD/2
      =12x5/2
      =60/2
      =30cm
6. L=DxD/2
      =8x15/2
      =120/2
      = 60cm
7. L= DxD/2
      =10x.../2
      =50m2
8. L= 70x100x.../2
      =7000x.../2
      = 0,874
9. L=pi x r x r
      = 22/7x21x21
      = 22/7x441
      = 1.386
10. D= L:pi
         = 1,54:3,14
         =154/100x100/314
         =154/314


semoga membantu saya sangat mintamaap kalo salah
