pliss bantu jawab keliling,sama luas nya aja
Jawab:
1. k = 54 cm
L = 168 cm²
2. k = 102 cm
L = 408 cm²
3. K = 2(a+b)
L = \frac{1}{2} × d1 × d2
Penjelasan dengan langkah-langkah:
1. K = 2(a+b)
= 2(10+17)
= 54 cm
L = \frac{1}{2} × d1 × d2
= \frac{1}{2} × 21 × 16
= 168 cm²
2. K = 2(a+b)
= 2(25+26)
= 102 cm
L = \frac{1}{2} × d1 × d2
= \frac{1}{2} × 17 × 48
= 408 cm²
3. K = 2(a+b)
L = \frac{1}{2} × d1 × d2
