Question

#20 what is the area of a rectangle with a length of 14 cm and a width of 9 cm?

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 \(l = 14\) cm and \(w = 9\) cm. Then \(A=14\times9\).

Step3: Calculate the product

\(14\times9=(10 + 4)\times9=10\times9+4\times9=90 + 36=126\)

Answer:

The area of the rectangle is \(126\) \(cm^{2}\)
