Answer:
Blue = 116 m^2
Step-by-step explanation:
The area of the path and the square = 30*30 = 900 m^2
The size of the square = 30 - 2 = 28. The square = 28^2 = 784
The path takes up the difference between the two 900 - 784 = 116
Answer:
x ≈ 6.2 cm
Step-by-step explanation:
using the cosine ratio in the right triangle
cosΘ = 
, that is
cos39° = 
= 
( multiply both sides by 8 )
8 × cos39° = x , then
x ≈ 6.2 cm ( to 1 dec. place )
To find that, just multiply 5x3 and your answer will be 15 :))
