Question

while waiting for the paint to dry, you start shopping for a large desk. one desk youre considering has a rectangular top thats 1.2 meters long and 0.7 meters wide. whats the area of the desktop? 3.8 m² 1.68 m² 0.84 m² 0.19 m²

Explanation:

Step1: Recall the formula for the area of a rectangle

The formula for the area \(A\) 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 \(l = 1.2\) meters and \(w=0.7\) meters. Then \(A=1.2\times0.7\).

Step3: Calculate the product

\(1.2\times0.7=(1 + 0.2)\times0.7=1\times0.7+0.2\times0.7 = 0.7+0.14=0.84\)

Answer:

\(0.84\ m^{2}\) (the third option)
