The answer is 1224. You do 70.5 + 65.5, divided by two, then you take that answer and multiply by 18 to get 1224

What is the area of a rectangle that is 3.1 cm wide and 4.4 cm long? Enter the full-precision answer first to see the correspond

Brrunno [24]

Answer: Without rounding : 13.64 (square cm)

Rounded answer : 13.6(square cm)

Step-by-step explanation:

We know that the area of a rectangle is given by :-

$A=l\times w$ , where l is the length and w is the width of the rectangle.

Given : The dimensions of a rectangle are 3.1 cm wide and 4.4 cm long.

Then, the area of rectangle will be:-

$A=4.4\times 3.1=\dfrac{44}{10}\times\dfrac{31}{10}\\\\=\dfrac{1364}{100}=13.64\text{ cm}^2\approx13.6\ cm^2 \text{Rounded to the nearest tenth}$

Therefore, the area of rectangle = $13.6\text{ cm}^2$

Answer:

$\boxed{-\frac{6}{\pi}}$

Step-by-step explanation:

The average rate of change over a interval is the slope m of the straight line joining the two points.

$m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }\\\\= \frac{-1 - 5}{ \pi - 0}\\\\= -\frac{ 6}{\pi }$

The average rate of change is $\boxed{-\frac{6}{\pi}}.$
