Q. Laura is drawing a rectangle. The width will be 3centimeters, and the area will be at least 18square centimeters. Let x represent the length of the rectangle. Which inequality describes the problem?Choices:(A) 3x≤18(B) 3x≥18Solve the inequality. Then, complete the sentence to describe the solution. The rectangle will be at least ____ centimeters long.
Identify formula: Step 1: Identify the formula for the area of a rectangle. The formula is Area=width×length. Here, width=3cm and Area≥18sq cm.
Substitute values: Step 2: Substitute the known values into the area formula to form an inequality. 18≤3x.
Solve inequality: Step 3: Solve the inequality for x. Divide both sides by 3 to isolate x. 18÷3≤x, so x≥6.
