length of rectangle is 6m less than three times the breadth. If its highlight%28cross%28perimer%29%29 perimeter is 148 m find dimension of the rectangle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

L = 3W - 6

L + W + L + w = 148 (perimeter !)  --->

(3W-6) + W + (3W-6) + W = 148,  --->

8W - 12 = 148  --->  8W = 160  --->  W = 160%2F8 = 20.

The width is 20 m.

Then the length is 3W -6 = 3*20-6 = 54 m.
