Answer:
a(x)=2x^2+9x+4
Step-by-step explanation:
We have been given the length and width, as well as the formula to find the area:
Length: 2x + 1
Width: x + 4
A = l * w
A = (2x + 1)(x + 4)
2x^2 + 8x + x + 4
We can add like terms now:
2x^2 + 9x + 4
Our area is 2x^2 + 9x + 4
Our answer would be a(x)=2x^2+9x+4
The correct answer is third option
a(x) = 2x² + 9x + 4
It is given that,the length of a rectangle is given by the function l(x)=2x+1, and the width of the rectangle is given by the function w(x)=x+4.
<u>To find the area of the rectangle</u>
Area of rectangle = Length * Breadth
a(x) = l(x) * w(x)
= (2x + 1)(x + 4)
= 2x² + 8x + x + 4
= 2x² + 9x + 4
