Answer:
The brace is 
ft ≅ 12.806 ft long
Step-by-step explanation:
The length of the diagonal of a rectangle can be found using this rule
, where
∵ The gate has shaped a rectangle
∵ Its length = 10 ft
∵ Its width = 8 ft
∴ l = 10 and w = 8
∵ The brace is the diagonal
→ By using the rule above
∴ 
∴ The length of the brace = ≅ 12.806 ft
∴ The brace is ≅ 12.806 ft long
Answer:
67,900
Step-by-step explanation:
Move the decimal place 4 spaces to the right.
If you draw that information out, you will see that the length is 12 and the width is 5
The area of a rectangle is given by the formula length *width
12*5 is 60
So, the area is 60 cm^2
