Please, let me answer your question :)___________________________
1/4 Lingkaran :
- r = 14 cm
Trapesium :
- a = 28 cm
- b = 14 + 20 = 34 cm
- t = 6 cm
Segitiga Siku - Siku :
- a = 20 cm
- t = 14 cm
Ditanya :
- L Lingkaran :...?
- L Trapesium :...?
- L Segitiga :...?
- L total :...?
LL = ¼ x π x r²
LL = ¼ x 22/7 x 14 x 14
LL = ¼ x 22 x 2 x 14
LL = ¼ x 44 x 14
LL = 11 x 14
LL = 154 cm²
LT = ½ x (a + b) x t
LT = ½ x (28 + 34) x 6
LT = ½ x 62 x 6
LT = 31 x 6
LT = 186 cm²
LS = ½ x a x t
LS = ½ x 20 x 14
LS = 10 x 14
LS = 140 cm²
L Total = 154 + 186 + 140
L Total = 480 cm²
Yg B jawabannya.
