Question

Malam kaa bantuin ya tolong..

Answer 1

Jawab:

Penjelasan dengan langkah-langkah:

K = 2p +2l

102 = 2p + 2l

p+l  = 102/2

p+l = 51

p-l  = 17

p    = 17 + l

p      + l =51

17 + l  + l = 51

2l + 17 =51

2l = 51- 17

   = 34

l    = 34/2

     = 17

L = p. l

   = (l +17) .l

   = (17 + 17) . 17

   =578 cm^2

Answer 2

K=2x(p+l)

=2x102

102:2=51 m

panjang=51-17=34 m x 2=68 m

lebar=102-68=34:2=17 m

L=p x l

=68 x 17

=1156 m2

maaf kalo salah...
