Can someone me with this question

STEP 1:
Set a ratio to determine the side length of triangle TUV. Since the two triangles are similar, the sides are proportional.

x= side length of TUV

6m/8m= 15m/x
cross multiply

(6*x)= (8*15)

6x= 120
divide both sides by 6

x= 20m side of TUV

STEP 2:
Add sides of triangle TUV

Perimeter= 20m + 20m + 8m
Perimeter= 48m

ANSWER: The perimeter of triangle TUV is 48m (bottom answer).

Hope this helps! :)
