Question

the length of a rectangle is 2.5 in and the width is 4.9. what is the area? (area = length × width)

Explanation:

Step1: Recall the area formula

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

Given \(l = 2.5\) in and \(w = 4.9\) in. Substitute into the formula: \(A=2.5\times4.9\).

Step3: Calculate the product

\(2.5\times4.9=(2 + 0.5)\times4.9=2\times4.9+0.5\times4.9 = 9.8+2.45=12.25\) in².

Answer:

12.25 in²
