Question

a rectangular red sticker is 15 millimeters tall and 17 millimeters wide. what is its area? square millimeters

Explanation:

Step1: Recall the formula for the area of a rectangle

The area formula for 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

Here, \(l = 17\) mm and \(w = 15\) mm. So \(A=17\times15\).

Step3: Calculate the product

\(17\times15=(10 + 7)\times15=10\times15+7\times15=150 + 105=255\).

Answer:

255
