Answer is dm².
In order to calculate the area of the board that can be seen, we need to calculate the area of the the rectangular board and the circular frame. The difference of both's area is the required answer.

Answer:
L = 68 ft
Step-by-step explanation:
To find the perimeter of something you need to add up all the sides
In this case I am assuming Sam's property is a square/rectangle
- Which means the formula for the perimeter is P = 2L + 2W
If L = 2W - 12 and P = 216, we can use these values and plug them into our perimeter equation to solve for w and then solve for l
- 216 = 2(2W -12) + 2W → ditributing the 2 to the (2w - 12) gives us
- 216 = 4W - 24 + 2W → combing like terms gives us
- 216 = 6W - 24 → adding 24 to both sides gives us
- 240 = 6W → dividing both sides by 6 gives us
- 40 ft = W
With the width being solved, we can now plug that value into our length equation
- L = 2(40) - 12 → distributing the 2 to the 40 gives us
- L = 80 - 12 → combing like terms give us
- L = 68 ft
Answer:
<h2>x=33 and y=12 7/11</h2>
Step-by-step explanation:
<h2> soln</h2><h2> ( 4x-3)+41=180</h2><h2> 4x+38=180</h2><h2>4x=180-38</h2><h2> 4x=142 </h2><h2>divide 4 both side with make value of x</h2><h2>x=33</h2>
<h2> and value of y is</h2><h2> soln </h2><h2>11y+6+45=180</h2><h2>11y+51=180</h2><h2>11y=180-51</h2><h2>11y=129</h2><h2>divide 11 both side with make value of y</h2><h2> y=12 7/11 this is my answer</h2>

-3b-4=11
-3b-4+4=11+4 (Move constants to the right by adding its opposite to both sides)
-3b=11+4 (Eliminate the opposites)
-3b/(-3)=15/(-3) (Divide by -3 on both sides)
b= (-5)
