Answer:

length=25 width=17

Step-by-step explanation:

l+w=42

start by guessing a pair of numbers that equals 42 i chose 22+20

since these two numbers are 2 digits apart,

5-2=3

now we have to add 3 to 22 and subtract 3 from 20

now it is 25+17 which still equals 42

Given:

$PQRS\sim TUVW$

In the given figure, PS=x, RS=35, UV=20, VW=25 and TW=15

To find:

The scale factor from PQRS to TUVW.

Solution:

We have,

$PQRS\sim TUVW$

We know that the corresponding sides of similar figures are proportional. The scale factor is the ratio of one side of image and corresponding side of preimage.

The scale factor is:

$k=\dfrac{VW}{RS}$

$k=\dfrac{25}{35}$

$k=\dfrac{5}{7}$

Therefore, the scale factor from PQRS to TUVW is $k=\dfrac{5}{7}$ .

NARA [144]

Answer:A
