Answer:
The length of the field is 84 yards
Step-by-step explanation:
Since the area of a rectangle is width times the length, we can write a simple equation.
Let w be the width
Let l be the length
W*L = 4284
Since we know the width of the rectangle is 51 yards, we can plug it in.
51L = 4284
Dividing 51 on both sides,
L = 84
