The length of the base of the rectangle is 11.9 yards if it has a perimeter of 57.6 yards.
We can determine the length of the base of the given rectangle by using the following for the perimeter as follows;
P = 2 ( L + W )
Here L represents length, W represents width and P represents the perimeter.
Since the height of the rectangle is 16.9 yards and we have to find the length of the base, the height can be considered to be the width of the rectangle. Therefore;
57.6 = 2 ( L + 16.9 )
57.6 = 2L + 33.8
2L = 57.6 - 33.8
2L = 23.8
L = 23.8 ÷ 2
L = 11.9
Therefore; the length of the base is calculated to be 11.9 yards.
