Question

find the area.
20 in
12 in
a = ? in²

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, \(l = 20\) in and \(w=12\) in.

Step3: Calculate the area

Substitute the values into the formula: \(A=20\times12\).
\(20\times12=(2\times10)\times12 = 2\times(10\times12)=2\times120 = 240\)

Answer:

\(240\)
