Question

Help please Don't understand how to solve Will medal.

Square QRST is similar to square KLMN. The ratio of the length of side QR to the length of side KL is 3:2. If side ST = 15 cm, what is the length of side LM?https://media.studyisland.com/pics/159441no1.png

Answer 2

what you know about the sides of a square ? how are they ?

Answer 3

with different lengths ?

Answer 4

?I don't understand the question sorry.

Answer 5

use proportionalitie of corespondent sides - do you know it how ?

Answer 6

,,corespondent " is indifferent bc. the square has every sides equali - yes ?

Answer 7

so than you know that

QR/KL = 3/2 so this mean that ST/KL need being equal 3/2 too

so this mean that you can writing bc. ST=15

15/LM = 3/2 can you solve it for LM ?

Answer 8

@surjithayer do you like interfering ,why ?

Answer 9

I'm sorry guy's I'm still really confused I feel really stupid right now

Answer 10

@harleygirl18

Lengths of corresponding sides of similar polygons are in proportion. Recall that squares are equilateral.

Picking up from the work of @jhonyy9 ,

15/LM = 3/2 can you solve it for LM ?
