Question

If WY/RT = 6/5 and the area of triangle QRS = 75 cm^2, calculate the area of triangle XYZ.
a. 52.1 cm^2
b. 62.5 cm^2
c. 90 cm^2
d. 108 cm^2

Answer 1

whats the equation for the area of a triangle?

Answer 2

a=bh

Answer 3

1/2bh

Answer 4

and also what do u think XZ/QS=?

Answer 5

??

Answer 6

do u realize the trianglesr similar?

Answer 7

and do u realize that WY/RT is the ratio ofthe height of the similar triangles there?

Answer 8

yes

Answer 9

good now what do u think the ratio of the bases will b?

Answer 10

QS is7.5

Answer 11

XZ is 9

Answer 12

hmmm u shoouldnt b able to solve for any lengths in this problem

Answer 13

it is d. a is 108. b/c base of xyz is 36 and base of qrs is 30

Answer 14

is this correct?

Answer 15

it is 108

Answer 16

ok i got that. thank you

Answer 17

all u had to do was multiply the area of the small triangle by (6/5)^2

Answer 18

ya i know thanks
