This is a simple equation:
x - 7 < 14
x < 14 + 7
x < 21
→ Many people think that because there is not "=" sign they don't flip the sign of what in this case is -7. But actually, the symbols "<" and ">" act as the equal sign. This rule doesn't apply to positive number, only negative.

Answer:
A:
The perimeter of the parking lot is 302 yards.
The area of the parking lot is 5,544 yards squared.
B: Perimeter
C: Area
Step-by-step explanation:
A:
To find the perimeter of the parking lot, we add all the sides up. 2L + 2W = Perimeter.
2(63) + 2 (88) = 302
To find the area, we multiply the length by the width. 63 × 88 = 5,544.
B: We need to know the amount of chain needed to surround the parking lot. In other words, we need to line the perimeter with a chain.
C: We would be paving the entire area of the parking lot.
