Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2(L+W)
L is the length of the triangle
W is the width
If the perimeter of a rectangle is represented by the expression
In order to know what wat each part represents, we will rewrite the given equation in the form 2(L+W).
Given
Perimeter of a rectangle
Compare the given function with the perimeter to get L and W
Hence the following statements explain correctly what each part of the expression represents
- One side of the rectangle measures x (the length)
- One side of the rectangle measures 3x + 1 (the width)
- 2 is the coefficient in each term that represents 2 lengths and 2 widths in a rectangle.
