A.bentuk bangun = persegi luas = s x s = 15 x 15 = 225 keliling = 4 S = 4 ( 15) = 60
2. bentuk bangun = persegi panjang luas = P x L = 8 x 20 = 160 keliling = 2P + 2 L = 2 ( 8) + 2 ( 20) = 16 + 40 = 56
3. bentuk bangun = persegi luas = S x s = 7,5 x 7,5 = 56,25 keliling = 4 S = 4 7,5 = 30
keliling= 15 x 4= 60 cm
b. luas= 8 x 20 = 160
keliling= (8 x 2) + ( 20 x 2)= 16 + 40= 56 cm
c. luas= 7,5 x 7,5 = 56,25
keliling=4 x 7,5 = 30 cm
luas = s x s
= 15 x 15
= 225
keliling = 4 S
= 4 ( 15)
= 60
2. bentuk bangun = persegi panjang
luas = P x L
= 8 x 20
= 160
keliling = 2P + 2 L
= 2 ( 8) + 2 ( 20)
= 16 + 40
= 56
3. bentuk bangun = persegi
luas = S x s
= 7,5 x 7,5
= 56,25
keliling = 4 S
= 4 7,5
= 30
