Answer:
200 cm^2
Step-by-step explanation:
Add up all areas
4 x 6 x 1/2 = 12
4 x 6 x 1/2 = 12
3 x 11 = 33
3 x 11 = 33
6 x 11 = 66
12 + 12 + 33 + 33 + 66 = 200
Answer:
22.07 ft & 9.32 ft
Step-by-step explanation:
by sines rule :
20/sin 65° = r/sin 90° = y/sin 25°
r = 20×sin 90°/sin 65° = 20/0.9063
= 22.07 ft
y = 20×sin 25°/sin 65° =
20× 0.4226/0.9063
= 9.32 ft
