Final answer:
To find the perimeter of the rectangle, use the formula P = 2(length + width), where the length is 8x + 3 and the width is 5F. To find the area of the rectangle, use the formula A = length × width, where the length is 8x + 3 and the width is 5F.
Step-by-step explanation:
To simplify the expression for the perimeter of the rectangle, we need to find the sum of all sides of the rectangle.
The formula for the perimeter of a rectangle is P = 2(length + width).
In this case, the length is 8x + 3 and the width is 5F. Therefore, the perimeter is P = 2(8x + 3) + 2(5F).
To simplify the expression for the area of the rectangle, we need to multiply the length and width of the rectangle. The formula for the area of a rectangle is A = length × width.
In this case, the length is 8x + 3 and the width is 5F. Therefore, the area is A = (8x + 3)(5F).
