Step-by-step explanation:
<u>We know that:</u>
- Perimeter of a rectangle = Sum of all its sides
- Length of rectangle = 4x² - x + 2
- Width of rectangle = 5x - 3
To find the perimeter, we need to use the equation "Perimeter of a rectangle = Sum of all its sides".
<u>Solution:</u>
- Perimeter of a rectangle = Sum of all its sides
- => 2[{4x² - x + 2} + {5x - 3}] = Perimeter
- => 2[4x² - x + 2 + 5x - 3] = Perimeter
- => 2[4x² + {-x + 5x} + {2 - 3}]
- => 2[4x² + 4x - 1]
- => 8x² + 8x - 2
Hence, the perimeter of the rectangle is 8x² + 8x - 2.
The area of the shaded triangle formed as the result of the overlap is = 62.35 inches ²
<h3>Calculation of the equilateral triangle</h3>
After folding the rectangle with length of 12 inches and width of 18 inches, an equilateral triangle was formed.
An equilateral triangle is a type of triangle where by all the three sides are equal.
To determine the value of one of the sides, CB or CD is used because the folding didn't affect these sides.
Using the formula for the area of an equilateral triangle,
A = √¾ a²
a= 12 inches
A = √¾ ×12²
A = 62.35 inches ²
