Question

The length of a rectangle is x. The width of the rectangle is (x + 10). Write an expression for the area of the rectangle.

Answer 1

Answer:

$A=x^2+10x$

Step-by-step explanation:

Area of a Rectangle

Given a rectangle of width W and length L, its area can be calculated with the formula:

A = WL

We are given the length of a rectangle is L=x and the width is W=x+10, thus the area is:

$A=x(x+10)$

Multiplying:

$\mathbf{A=x^2+10x}$
