The grassy area of a playground has a side length of x and a side of width of x + 3 what is the area of the playground?

A. A (x) = x^2+3x

B. A (x) = x^2+x+3

C. A (x) = 2x+3

D. A (x) = x^2+3

A

Step-by-step explanation:

Area = length * width

Area = x * (x + 3)

A (x) = x² + 3x

A

Step-by-step explanation:

We assume this playground is a rectangle. The area of a rectangle is of the form: A = lw, where l is the length and w is the width.

Here, the length is l = x and the width is w = x + 3. So, plug these in:

A = lw

A = x (x + 3)

Expand this out:

A = x² + 3x

The answer is thus A.
