Question

a rectangular board is 1.8 meters long and 1.25 meters wide. what is the area of the board in square millimeters? do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Convert length and width to millimeters

Since \(1\) meter \( = 1000\) millimeters.
The length \(l = 1.8\) meters \(=1.8\times1000 = 1800\) mm.
The width \(w = 1.25\) meters \(=1.25\times1000=1250\) mm.

Step2: Calculate the area of the rectangle

The area formula for a rectangle is \(A=l\times w\).
Substitute \(l = 1800\) mm and \(w = 1250\) mm into the formula:
\(A=1800\times1250\)
\(A = 2250000\) \(mm^{2}\)

Answer:

\(2250000\) \(mm^{2}\)
