The length of a rectangle is triple the width. The perimeter is 54 m. Find the dimensions of the rectangle
+15 width*3 = length
length + width + length + width = 54
2(3w + w) = 54
8w = 54
width = 6.75
6.75*3 = 20.25
length = 20.25
So the dimensions of the rectangle are length*width:
20.25*6.75 = 136.6875
