Question

Berapa keliling bangun datar tersebut?

Answer 1

K persegi pnjang
= 2(p+l)
= 2(14cm+8cm)
= 28 cm + 16 cm
= 44 cm

k setengah lingkaran
= 22/7 x 14 cm
= 44 cm

k segitiga sikusiku
x2 = (6cm)2 + (8cm)2
x2 = 36 cm2 + 64 cm2
x2 = 100 cm2
x = 10 cm
k segitiga
6 cm + 8cm + 10 cm
24 cm


total keliling = 44 cm + 44 cm + 24 cm
= 112 cm
