Question

A rectangular board is 1300 millimeters long and 900 millimeters wide. What is the area of the board in square meters? Do not round!

Answer 1

1300 mm = 1.3 m

900 mm = 0.9 m

Area

1.3 * 0.9 = 1.17 m²

Answer 2

Since the answer asks for meters, let's convert to meters right at the start. There are 1000 millimeters in 1 meter, we can convert the dimensions:

Length: $\frac{1300}{1000} =1.3m$

Width: $\frac{900}{1000}=0.9m$

So to find the area of the board, we will use the equation: $A=l*w$

$A=1.3*0.9$

$A=1.17 m^{2}$

So now we know that the area of the board is $1.17m^{2}$.
