Question

1. this rectangle has an area of 42 square centimeters. what is the missing length? use an equation to explain.

Explanation:

Step1: Define variables and formula

Let \( x = \) missing length. Area of rectangle: \( \text{length} \times \text{width} = 42 \). So \( 6x = 42 \).

Step2: Solve for x

Divide both sides by 6: \( x = \frac{42}{6} = 7 \).

Answer:

7 cm
