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?

Respuesta :

Answer: 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%
