You just have to divide the 856.8 by 28
Area of a rectangle is
A=lh
Since you’re looking for the length you just have to divide each side by the width to get the answer and in this case the height is the width

Answer:

30.6

Step-by-step explanation:

A = b*h

where b is the base, h is the height and A is the area

856.8 = b*28

Divide each side by 28

856.8/28 = 28b/28

30.6 =b
