Two similar right triangles have areas of 6 square inches and 150 square inches. The length of the hypotenuse of the smaller triangle is 5 inches. What is the sum of the lengths of the legs of the larger triangle?

Hint: Right triangles, hypotenuse=5..Does that take you somwhere? You can use the Pythogorean Triplets to rememeber.

The scalle factor  of the larger triangle to the smaller  = 

 

sqrt  [ larger area / smaller area ] =    

 

sqrt  [ 150 / 6]  =

 

sqrt (25)   =  5

 

The legs of the smaller triangle are   3  and 4

 

The legs of the larger triangle are each  5 times as much =  15 and 20

 

So...the sum of the legs of the lager triangle   = 15 + 20   = 35 units
