To find the perimeter you have to combine like terms. 8x + 5x - 6x is 7x and 6 - 5 + 12 is 13 so the perimeter of the triangle is 7x + 13
The area of the rectangular base is the amount of space on the rectangular base
The area of the rectangular base is 60 square inches
<h3>How to determine the area of the rectangular base?</h3>
The question is incomplete; as the diagram is not given.
So, I will apply the concept of similar shapes to determine the area of the rectangular base
To determine the area of the rectangular base, we make use of the following equivalent ratio:
Ratio = Height : Area
This gives
3 : 36 = 5 : Area
Express as fraction
36/3 = Area/5
Evaluate the quotient
12 = Area/5
Multiply both sides by 5
Area = 60
Hence, the area of the rectangular base is 60 square inches

Answer:
irrational
Step-by-step explanation:
Use the Pythagorean theorem.
5² + 6² = c²
25 + 36 = c²
c² = 61
7² = 49
6² = 64
61 is between 7² and 8², so it is not rational.
