Question

The dimensions of a rectangle are 5x+3 and 4x - 6. Write an expression that represents the perimeter the rectangle.

Answer 1

The perimeter of a Rectangle.

`\begin{gathered} Perimeter\text{ of a rectangle = 2(L+}B) \\ \text{ P = 2\lbrack(5x+3)}+(4x-6)\rbrack \\ P=2(5x+3+4x-6) \\ P=\text{ 2(5x+4x+3-6)} \\ P=2(9x-3) \\ P=18x-6 \end{gathered}`

The correct expression for the required perimeter is 18x - 6
