Answer:
Perimeter = 120 inches
Area = 176 inches 2
Step-by-step explanation:
For perimeter, all you have to do is add. For area, you would normally have to multiply, but since the numbers are all squared, all you have to do is add them
9 + 1/2 (7n - 26) - 8n
Expand brackets by multiplying by 1/2:
9 + 3.5n - 13 - 8n
Collect like terms:
4.5n - 4
Turn it into an equation:
4.5n - 4 = 0
Isolate 4.5n by adding 4 to both sides:
4.5n = 4
Divide both sides by 4.5 to get the value of n:
n = 8/9
