Question

Jawab pake rumus dan cara

Answer 1

Luas layang layang = d1*d2
250 mkuadrat = 20 cm*d2
maka d2/AC = 250/20
AC=12,5

Answer 2

6) 1/2.d1.d2 
  = 1/2 (8+8)(15+6)
= 1/2.16.21
=8.21
=168 cm²

7) BD = 20 cm
    L= 250 m² --> 2.500.000 cm²
    AC= Luas/d1 x 2
    AC = 2.500.000/ 20 x 2
    AC = 62.500 cm  
(Itu soalnya ga salah yaa,,, 250 m² ._.)

(kalau misalkan ternyata luasnya 250 cm²)
AC= 250cm²/20 x 2
AC= 250 / 40
AC = 6,25 cm
