Answer:
the common difference is 6.
Step-by-step explanation:
Given;
first term of an AP, a = -7
let the common difference = d
The third term is written as;
T₃ = a + 2d
The eight term is written as;
T₈ = a + 7d
The ratio of the eight term to third term = 7:1

Therefore, the common difference is 6.
Area of rectangle = width * length
So,
A = 75 * 18
A= 1350 inch^2
Convert inches to feet
1350 * 0.0833 = 112.5 ft^2
