The length of side walk is 500 feet
Solution:
Given that, A rectangle park measures 300 ft by 400 ft
Length = 300 feet
Width = 400 feet
A sidewalk runs diagonally from one comer to the opposite corner
We have to find the length of side walk
Which means, we have to find the length of diagonal of rectangle
The diagonal of rectangle is given by formula:
Where,
d is the length of diagonal
w is the width and l is the length of rectangle
Substituting the values in formula, we get
Thus length of side walk is 500 feet
