Martin is building a rectangular fire pit in his backyard. He dug a hole 30 inches by 30 inches. He decides to make each side of the pit 6 inches longer. What is the percent increase in the area of the fire pit?

44%

Step-by-step explanation:

Area of the first hole = 30 × 30 = 900

Area of second hole = (30+6) × (30+6) = 36 × 36 = 1296

Percentage increase = (1296 - 900) / 900 × 100

= (396 / 900) × 100

= 44%

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope
