tolong ya di bantu jawab kak pake cara ya

1. L.PersegiPanjang = p × l
= 80 × 60
= 4.800 cm²

2. L.Persegi = s × s
2.500 = s × s
s = √ 2.500
s = 50 cm
Jadi , AB adalah 50 cm

3. L.Segitiga = ½ × a × t
= ½ × 60 × 40
= ½ × 2.400
= 1.200 cm²

4. L.JajarGenjang = a × t
= 10 × 8
= 80 m²

Semoga Membantu :) Maaf kalo salah

1.pxl = 80 x 60 = 4800 cm²

2.L = 2500 cm² 
  AB = sisi = √2500
                  =50 cm
3.L = 1/2 at
      =1/2 40*60
      = 1/2*2400
      = 1200 cm²
4.L =axt
      = 10 x 8
      = 80 cm²

semoga bantu yaaa
