Answer:
Height = 2 yards
Longer base = 8 yards
Explanation:
From the figure attached :
The length of the shorter base of the Trapezoid = 4 yards
Hence, if height of Trapezoid is half the length of the shorter base ;
Then ;
Height of Trapezoid = shorter base/2 = 4 /2 = 2 yards
Longer base is twice the length of shorter base :
Longer base = 2 * shorter base = 2 * 4 = 8 yards
