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

$Area=Length\times width$

$Area=(2x+3)\times (x+6)$

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

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

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