You have a rectangle and 2 triangles:
rectangle = 12 *6 = 72
larger triangle on left, find the base:
base = 6 / tan(45) = 6
area = 1/2 x b x h = 1/2 x 6 x 6 = 18
smaller triangle:
area = 1/2 x b x h
1/2 x 2 x 6 = 6
total area:
72 +6 +18 = 96 cm^2
Answer:
c=13.7 meters
Step-by-step explanation:
The 7.7 meters and 6 meters added together equal 13.7
If you take 0.98 and multiply by 2.5 you get 2.45 so there is no better deal. ☺
