Question

(1) the length of a rectangle is 10 cm. what is the width if the area is 60 cm²? answer:

Explanation:

Step1: Recall area formula of rectangle

The area \( A \) of a rectangle is given by the formula \( A = l \times w \), where \( l \) is the length and \( w \) is the width.

Step2: Substitute known values and solve for width

We know that \( A = 60 \, \text{cm}^2 \) and \( l = 10 \, \text{cm} \). Substituting these values into the formula, we get \( 60 = 10 \times w \). To find \( w \), we divide both sides of the equation by 10: \( w=\frac{60}{10} \).

Step3: Calculate the width

Simplifying \( \frac{60}{10} \), we get \( w = 6 \, \text{cm} \).

Answer:

The width of the rectangle is \( 6 \, \text{cm} \).
