You own a square plot of land and you want to determine its surface area. You know that one side of land measures 10 longer than what the appraisers estimated, but you lost the paperwork with the information. Write an expression to represent the area of your land.

What is the area of the property if x = 12?

Respuesta :

The area of the property is the product of its dimensions, and the expression for the area is (x + 10)²

How to determine the expression for area?

The area of the land is the product of its dimensions.

Let the length and the width of the land be x.

So, the area measured by the appraisal is:

Area = x²

One side of the land is 10 more than the measured length.

So, we have:

Area = (x + 10)²

Substitute 12 for x

Area = (12 + 10)²

Evaluate

Area = 484

Hence, the area of the property is 484
