Question

A rectangular board is 1200 millimeters long and 800 millimeters wide. What is the area of the board in square meters? Do not round your answer. Be sure to include the correct unit in your answer.

Answer 1

Given:

shape: rectangle

length: 1200 mm

width: 800 mm

Find: area in square meters

Solution:

First, let's convert the given dimensions to meters.

Conversion rule is 1 m = 1000mm. Let's convert the length first.

$1200\operatorname{mm}\times\frac{1m}{1000\operatorname{mm}}=1.2m$

Length = 1.2 meters

Now, let's convert the width.

$800\operatorname{mm}\times\frac{1m}{1000\operatorname{mm}}=0.8m$

Width = 0.8 meters

Now that we are done converting the dimensions of the board to meters, let's solve for the area. The formula is:

$Area=length\times width\text{ }$

Let's plug in the converted dimensions to the formula.

$Area=1.2m\times0.8m=0.96m^2\text{ }$

Therefore, the area of the board is 0.96 square meters.
