1200 mm long and 800 mm wide. What is the area in square meters
alexgriva [62]

Answer: 0.96\ m^2

Step-by-step explanation:

We can make the conversion from milimeters to meters (Remember that 1m=1,000\ mm). Then:

1,200\ mm to m:

(1,200\ mm)(\frac{1\ m}{1,000\ mm})=1.2\ m

800\ mm to m:

(800\ mm)(\frac{1\ m}{1,000\ mm})=0.8\ m

Now, we need to use this formula for calculate the area of a rectangle:

A=lw

Where "l" is the lenght and "w" is the width.

Knowing that:

l=1.2\ m\\w=0.8\ m

We can substitute values into the formula. Then we get:

A=(1.2\ m)(0.8\ m)\\\\A=0.96\ m^2
