DochEvi [55]

The length of side walk is 500 feet

<em><u>Solution:</u></em>

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

<em><u>The diagonal of rectangle is given by formula:</u></em>

d = \sqrt{w^2+l^2}

Where,

d is the length of diagonal

w is the width and l is the length of rectangle

<em><u>Substituting the values in formula, we get</u></em>

d = \sqrt{400^2+300^2}\\\\d = \sqrt{160000+90000}\\\\d = \sqrt{250000}\\\\d = 500

Thus length of side walk is 500 feet
