tolong dong buat besok sekalian pake cara 1 sampe 10 y

1) L = s × s
625 = s²
s = √625
s = 25 cm ( B )

2) L = π × r²
= 22/7 × 10,5 × 10,5
= 346,5 cm² ( A )

3) L = ½ × d1 × d2
192 = ½ × 24 × d2
192 = 12 × d2
d2 = 192 ÷ 12
d2 = 16 cm ( D )

4) L1 = s × s
= 20 × 20
= 400 cm²
L2 = ½ × π × r²
= ½ × 3,14 × 10 × 10
= 157 cm²
Lb = 400 - 157
= 243 cm² ( B )

5) L1 = ½ × a × t
= ½ × 12 × 12
= 72 cm²
L2 = π × r²
= 3,14 × 3 × 3
= 28,26 cm²
Lb = 72 - 28,26
= 43,74 cm² ( A )

6) L = π × r²
50,24 = 3,14 × r²
r² = 50,24 ÷ 3,14
r = √16
r = 4 cm ( B )

7) L = s × s
196 = s²
s = √196
s = 14 cm
r = s = 14 cm
L½ = ½ × π × r²
= ½ × 22/7 × 14 × 14
= 308 cm² ( A )

8) L1 = p × l
= 20 × 10
= 200 cm²
L2 = 2 × ½ × a × t
= 2 × ½ × 10 × 10
= 100 cm²
Lb = 200 - 100
= 100 cm² ( C )

9) L1 = ½ × π × r²
= ½ × 22/7 × 14 × 14
= 308 cm²
L2 = ½ × π × r²
= ½ × 3,14 × 4 × 4
= 25,12 cm²
L3 = ½ × π × r²
= ½ × 3,14 × 10 × 10
= 157 cm²
Lb = 308 - 25,12 - 157
= 125,88 cm² ( tdk ada opsi)

10) L = ½ × a × t
= ½ × 16 × 20
= 160 cm²
L2 = ½ × a × t
= ½ × 10 × 20
= 100 cm²
Lb = 160 - 100
= 60 cm² ( A )
