Question

find the area.
27 cm
12 cm
a = ? 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: Identify the length and width

Here, \(l = 27\) cm and \(w = 12\) cm.

Step3: Calculate the area

Substitute the values into the formula: \(A=27\times12\).
Using multiplication: \(27\times12=(30 - 3)\times12=30\times12-3\times12 = 360-36=324\) \(cm^{2}\).

Answer:

324
