The length of a plot land is 10 more feet than its width x. Write a simplified expression in standard from to represent the area of the land

a = x(x + 10)

Step-by-step explanation:

Let A be the area of the land.

X * X would work for a square area of land, but the length is 10 feet longer than the width,l so it would be a = x(x + 10), instead of a = x(x).

(x^2)+10x

Step-by-step explanation: Start with x times x+10

the correct is answer is a 9-sided polygon!
