Question

what is the area of a rectangle with a length of 4 centimeters (cm) and a width of 2 cm?
a 6 cm²
b 8 cm²
c 12 cm²
d 36 cm²

Explanation:

Step1: Recall the formula for the area of a rectangle

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

Step2: Substitute the given values into the formula

Given \(l = 4\space cm\) and \(w = 2\space cm\), we substitute into the formula: \(A=4\times2\).

Step3: Calculate the product

\(4\times2 = 8\).

Answer:

B. \(8\space cm^{2}\)
