The scale factor of rectangle jklm to rectangle qrst is . the perimeter of rectangle qrst is 12 units, and the perimeter of rectangle jklm is units. the area of rectangle qrst is units2, and the area of rectangle jklm is 128 units2. if proportional dimensional changes are made to a figure, then the perimeter will change by the scale factor, and the area will change by the scale factor.

step-by-step explanation:

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

1/4 because there is 4 grades.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
