A triangle has legs that measure 3 feet, 5 feet, and 7 feet. Calculate the dimensions of a similar triangle whose longest side measures 13 inches
***
7 ft=84 inches
multiply each dimension by 13/84:
13/84( 3 feet, 5 feet, and 7 feet)=(39/84 ft, 65/84 ft, 91/84 ft)=(5.57 inches, 9.29 inches, 13 inches)
dimensions of a similar triangle in inches: 5.57 by 9.29 by 13

-------------
Call the side of the 2nd triangle that is
parallel to the 3' side
-------------
Call the side of the 2nd triangle that is
parallel to the 5' side
-------------
Now I can say:

and

--------------
The dimensions are:
