Question

Franklin is drawing a rectangle. The length will be 5 inches, and the area will be at least 20
square inches.
Let x represent the width of the rectangle. Which inequality describes the problem?

Answer 1

Given:

Length of the rectangle = 5 inches

Width of the rectangle = x

Area of the rectangle is at least 20 square inches.

To find:

The inequality for the given problem.

Solution:

Let x represent the width of the rectangle.

We know that the area of a rectangle is:

$Area=Length\times Width$

$Area=5\times x$

$Area=5x$

It is given that, the area of the rectangle is at least 20 square inches. It means the area of the rectangle must be greater than or equal to 20.

$5x\geq 20$

Therefore, the required inequity for the given problem is $5x\geq 20$.
