Question

Nyatakan bangun berikut dalam bentuk aljabar

Answer 1

(a)
panjang sisi = a+a = 2a
K = 4 x panjang sisi
K = 4 × 2a
K = 8a

(b)
panjang = a+a+a = 3a
lebar = b+b+b = 3b
K = (2×p) + (2×l)
K = (2×3a) + (2×3b)
K = 6a + 6b

(c)
K = d + a + b + c + (b - d) + (a - c)
K = d + a + b + c + b - d + a - c
K = d - d + a + a + b + b + c - c
K = 2a + 2b
