We can use the Pythagorean Theorem here.....the ladder represents the hypotenuse of a right triangle...so...

ladder length = √[ 34^2 + 15^2 ] = √ [ 1381 ] ≈ 37.16 ft

Thank you so very much for that So I see your squaring the legs and then the sum of those two squared number's squared is the lenght of the hynoptiuse?

Close.....the square root of the sum of the squares of the leg lengths = the hypotenuse

Look at it this way

leg 1^2 + leg 2^2 = hypotenuse^2 take the square root of both sides

√ [ leg 1^2 + leg 2^2 ] = hypotenuse

Oh so you must square the sum of the legs squared legs or aka square the sum of a^2 + b^2

Not "square" the sum of the squares of the legs....but....take the * square root* of the sum of the legs squared
