Question

1200 mm long and 800 mm wide. What is the area in square meters

Answer 1

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:

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