We are given length of the rectangle = 24 units.
Width of the rectangle = 11 units.
We know, the formula for periemter of the rectangle as following
P = 2 * length + 2* width.
Let us plug values length = 24 units and width 11 units. We get
P = 2*24 + 2*11
P = 48 +22
P = 70 units.
We got perimeter of 70 units for length 24 units and width 11 units of the rectangle.
So, when its width w is 11 units with the length 24 units, the perimeter P of the rectangle can not be 60 units.
