From the qeustion, we are given the following parameters
Length of the triangle = 1/2 yard
Width of the triangle = 11/4 yards
Since we are not told what to look for, we can as well look for the area and perimeter of the rectangle.
Area of a rectangle = Length * breadth
Area = 1/2 * 11/4
Area of the triangle = 11/8 yd^2
For the perimeter:
perimeter of a rectangle = 2(L+W)
perimeter of the rectangle = 2(1/2+11/4)
perimeter of the rectangle = 2(2+11)/4))
perimeter of the rectangle= 2(13/4
perimeter of the rectangle = 26/4
perimeter of the rectangle = 13/2 yards
