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

Find the midpoint of the line segment with end coordinates of:<br> (-3,-1) and (-4,2)
fgiga [73]

Answer:

(- 3.5, 0.5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( \frac{x_{1}+x_{2}  }{2}, \frac{y_{1}+y_{2}  }{2} )

Here (x₁, y₁ ) = (- 3, - 1) and (x₂, y₂ ) = (- 4, 2) , then

midpoint = ( \frac{-3-4}{2}, \frac{-1+2}{2} ) = ( \frac{-7}{2}, \frac{1}{2} ) = (- 3.5, 0.5 )
