The perimeter of the park is 3x^2 + 37x - 4
<h3>How to determine the perimeter?</h3>
The side lengths of the triangular park are:
10x + 3x^2 - 8, 12x and 15x + 4
Add these sides to determine the perimeter
P = 10x + 3x^2 - 8 + 12x + 15x + 4
Collect the like terms
P = 3x^2 + 10x + 12x + 15x - 8 + 4
Evaluate the sum
P = 3x^2 + 37x - 4
Hence, the perimeter of the park is 3x^2 + 37x - 4

Hello from MrBillDoesMath!
Answer:
89 square meters
Discussion:
The area of the figure is the area of the full rectangle minus the area of the triangle
.
Rectangle area = 13 * 8 = 104
Triangle area = 1/2 bh = 1/2 ( 13 - 4 -4) * 6 = 1/2(5)*6 = 15
So the area of the figure - 104 = 15 = 89

Answer:
<h3>
x = 1/2</h3>
Step-by-step explanation:
-3x + 1 + 10x = x + 4
-1 -1
7x = x + 3
-x -x
6x = 3
÷6 ÷6
x = 1/2
