Question

The width of a​ rectangle, in​ feet, is represented by left parenthesis 3 x minus 1.5 right parenthesis. The length of the​ rectangle, in​ feet, is represented by left parenthesis 1.25 x plus 3 right parenthesis. Find the perimeter of the rectangle.

Answer 1

Answer:

Therefore Perimeter of the Rectangle is (8.5x +3) feet.

Step-by-step explanation:

Given:

Let Width and Length of a Rectangle be,

Width = ( 3x - 1.5 ) feet

Length = ( 1.25x + 3 ) feet

To Find:

Perimeter of the Rectangle = ?

Solution:

We have,

$\textrm{Perimeter of the Rectangle}=2(Length+Width)$

Substituting the given values in above formula we get

$\textrm{Perimeter of the Rectangle}=2((1.25x+3)+(3x-1.5))\\\\\textrm{Perimeter of the Rectangle}=2(4.25x+1.5)=8.5x+3\ feet$

Therefore Perimeter of the Rectangle is (8.5x +3) feet.
