The widths of two similar rectangles are 10 m and 15 m. What is the ratio of the perimeters? Of the areas?

1 answer:

6 0

Area and perimeter are in the ratio of 1:3. but if u mean to ask about the ratio of perimeters & areas of both triangles. the answer would be 1:1

Ierofanga [76]

Answer:

slope: $\bold{m=3}$

equation: $\bold{y-2=3(x-1)}$

Step-by-step explanation:

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\(1,\,2)\ \implies\ x_1=1\,,\ y_1=2\\(0,\,-1)\ \implies\ x_2=0\,,\ y_2=-1\\\\m=\dfrac{-1-2}{0-1}=\dfrac{-3}{-1}=3$

$y-y_1=m(x-x_1)$ - point-slope form of Equation of the Line

$x_1=1\,,\ y_1=2\,,\ m=3\\\\equation:\\{}\qquad\qquad y-2=3(x-1)$

This problem just occured to me that i cant do welp time to ask for some help asap

sweet [91]

Answer:

845

Step-by-step explanation:

Because they are similar triangles you can find the scale factor first.

395/553 is the scale factor

(395/553)*280=200

(395/553)*350=250

200+250+395 = 845

Find slope of both

(11,2)
(22,4)

$\\ \tt\hookrightarrow m=\dfrac{4-2}{22-11}=\dfrac{2}{11}=1.8$

(0,0)
(5,1)

$\\ \tt\hookrightarrow m=\dfrac{1-0}{5-0}=\dfrac{1}{5}=0.2$
