Ayo saya butuh bantuan yg bisa jawab dgn cara + benar pahala baginyaa aminn

2(p+l) = 200
2((6x+1)+(2x+3)) = 200
8x+4 = 200÷2
8x+4 = 100
8x = 100-4
8x = 96
x = 96÷8
= 12

l = 2x+3
= 2×(12)+3
= 24+3 = 27 cm

Pakai rumus kell
K = 2(p + l)
200 = 2(6x + 1 + 2x + 3) <-- 2 m = 200 cm
200/2 = 8x + 4
100 = 8x + 4
100 - 4 = 8x
96 = 8x
x = 96/8 = 12

Lebar = 2x + 3
= 2(12) + 3
= 24 + 3
= 27 cm (a.)
