A man was walked along the hypotenuse across a right-triangle plot. The other two sides measured 30 m and 40 m respectively. Approximately how much distance saved by not walking along the sides? (in m)

A man was walked along the hypotenuse across a right-triangle plot. The other two sides measured 30 m and 40 m respectively. Approximately how much distance saved by not walking along the sides? (in m) Correct Answer 20

Given 

The other two side of triangle = 30 m and 25 m

Formula Used 

H² = P² + B²

Calculation 

Hypotnuese = √(30² + 40²) = 50 m 

So, Total distance along the sides = 30 m + 40 m = 70 m 

then, A man saved distance by not walking along the side = 70 - 50 = 20 m 

∴ The distance saved by not walking along the side is 20 m
