Question

(Help please) Find both the perimeter and the area of the following rectangle

2x+3
X+6
Perimeter:_____
Area:____

Answer 1

Given:

Length of a rectangle = (2x+3) units

Width of the rectangle = (x+6) units

To find:

The perimeter and the area of the rectangle.

Solution:

We know that, the perimeter of the rectangle is

`Perimeter=2(Length+Width)`

`Perimeter=2((2x+3)+(x+6))`

`Perimeter=2(3x+9)`

`Perimeter=6x+18`

The area of rectangle is

`Area=Length* width`

`Area=(2x+3)* (x+6)`

`Area=2x^2+12x+3x+18`

`Area=2x^2+15x+18`

Therefore,
`Perimeter=6x+18` and
`Area=2x^2+15x+18`.
