The perimeter of the rectangular rose garden distance outside the path is 57.6m.
Two equal lengths and two equal widths make up a rectangle. We must sum up the lengths of the rectangle's four sides in order to get its perimeter.
Since there are two of each side length, it is easy to accomplish this by simply adding the length and width and multiplying the result by two.
Perimeter = 2(length + breadth)
Calculation for the outside of the path.
Th initial length of park is 15m.
The increment of the length after the width of path is included is;
= 15 + 1.2 + 1.2 (for both side)
= 17.4m
Similarly, the initial width of the park is 9m.
After the increment of the path the width becomes,
= 9 + 1.2 + 1.2 (both side included)
= 11.4m
The perimeter of the rose garden is ;
P = 2( 17.4 + 11.4)
= 2×28.8
= 57.6m
Therefore, the rectangular rose garden has the perimeter of 57.6m.
