Jawab :3,8 m = 380 cm
K = 2p + 2l
380 = 2p + 2(l - 10)
380 = 2p + 2l - 20
400 = 4p
x = 100
Lebar = 100 - 10 = 90
Luas = 100 . 90 = 9000 cm² = 0,9 m²
K = 2P + 2L
380 = 2P + 2(P-10)
380 = 2P + 2P - 20
380 + 20 = 2P + 2P
400 = 4P
P = 400
Lebar = P - 10
= 100 - 10
= 90 cm
Luas = P x L
= 100 x 90
= 9000 cm²
=0,9 m²
