Verified answer

1. Luas=Panjang x lebar
Panjang=Luas : lebar
= 6630 : 78
= 85 m
Keliling=2 x (P+l)
= 2 x (85+78)
= 2 x 163
= 326 m
2. K=2 x (P + l)
P= K:2 - l
P= 90:2-18
= 45-18
= 27 m
L= P x l
= 27 x 18
= 486 m²
3. K = 2 x ( P+ l)
= 2 x (75+45)
= 2 x 120
= 240 : 2 ( jarak pepaya)
= 120 buah pohon pepaya
4. L = P x l
= 42 x 28
= 1176 m²
K = 2 x ( P + l )
= 2 x ( 42 + 28 )
= 2 x 70
= 140 m
