Question

the length of a rectangle is 2.5 in and the width is 4.9. what is the area? (area = length × width)
12.25 in²
2.4 in²
1.96 in²
7.4 in²

Explanation:

Step1: Substitute values into formula

Given \(length = 2.5\ in\) and \(width = 4.9\ in\), use \(Area=length\times width\). So \(Area = 2.5\times4.9\).

Step2: Perform multiplication

\(2.5\times4.9=(2 + 0.5)\times4.9=2\times4.9+0.5\times4.9 = 9.8+2.45=12.25\ in^{2}\)

Answer:

A. \(12.25\ in^{2}\)
