Question

if QP=25, MN=35, and SR=13, calculate the area of LMN.

Answer 1

i smell the stench of similar triangles

Answer 2

to solve the area, you need base and height. base is MN and height is LS agree?

Answer 3

height is LR*

Answer 4

\[\frac{25}{35}=\frac{LS}{LS+13}\]

Answer 5

Finally

Answer 6

I'm still a little unsure.

Answer 7

Solve that proportion. Reduce 25/35 then cross multiply and solve.

Answer 8

LS = 32.5 , but what am I supposed to do with that?

Answer 9

What are you trying to find?

Answer 10

The area of △LMN.

Answer 11

How do you find the area of a triangle?

Answer 12

Is there a formula or something?

Answer 13

½ × b × h

Answer 14

What is the base of your triangle?

Answer 15

Oh I get it now area is = 796.25
Thanks Mertsj!

Answer 16

That seems too big. How did you get that?

Answer 17

base is 35

Answer 18

1/2(35)(32.5+13)=1/2(35)(45.5)
Yep. Your answer is correct. Good job.
