Answer:
Step-by-step explanation:
Formula to get the area of a rectangle,
Area = Length × Width
Area of rides area = 30 × n
= 30n yds²
Area of the arcade = 30 × 40 yds²
Area of the whole field = Area of rides + Area of Arcade
Area = [30n + 30(40)] square yards
Length of whole field = (n + 40) yds
Width of whole field = 30 yds
Area of the whole field = 30(n + 40) square yards
