Substitute the known leg lengths into the formula to solve for the hypotenuse ( c2=a2+b2c squared equals a squared plus b squared c2=42+52c squared equals 4 squared plus 5 squared 3. Calculate Squares and Sum Square both numbers and add them together: c2=16+25c squared equals 16 plus 25 c2=41c squared equals 41 4. Find the Square Root by taking the square root of both sides: c=41c equals the square root of 41 end-root ✅ Result The length of the hypotenuse is 41the square root of 41 end-root
