Sagot :
The time he saves when walking diagonally is 8 seconds
How to find diagonal and side of a rectangle?
A rectangle has opposite sides equal to each other.
The angles are equal.
Therefore,
perimeter of a rectangle = 2l + 2w
where
- l = length
- w = width
Therefore,
distance of the diagonal =√ 50² + 120²
distance of the diagonal = √2500 + 14400
distance of the diagonal = √16900
distance of the diagonal = 130 feet
distance if he follows the length of the rectangle = 50 + 120 = 170 feet
Hence,
Time spent diagonally
5 = 130 / t
t = 130 / 5
t = 26 seconds
Time spent along the perimeter
5 = 170 / t
t = 170 / 5
t = 34 secods
Therefore,
Time he will save by walking diagonally = 34 - 26 = 8 seconds
