Let the distance from the beach to the parking lot = D

 

So we have [ by similar triangles ]

 

D / 18   = 32 / D       cross-multiply

 

D^2  = 32 * 18

 

D^2 = 576     take the square root of both sides

 

D = 24 m

 

 

The distance from the parking lot to the refreshmemt stand is the hypotenuse of a right triangle with legs 24 and 32....so the distance = √[ 24^2 + 32^2]  = √ [576 + 1024[  = √1600 = 40 m

 

 

cool cool cool
