Jawaban:

The original area of the fire pit is the product of its length and width:

Area = 20 inches x 20 inches = 400 square inches

After James increases each side of the fire pit by 4 inches, the new length and width become 20 + 4 = 24 inches. Therefore, the new area is:

New Area = 24 inches x 24 inches = 576 square inches

To find the percent increase in area, we need to calculate the difference between the new area and the original area, divide by the original area, and then multiply by 100 to convert the answer to a percentage:

Percent Increase = [(New Area - Original Area) / Original Area] x 100%

Substituting the values we have, we get:

Percent Increase = [(576 - 400) / 400] x 100%

Percent Increase = (176 / 400) x 100%

Percent Increase = 0.44 x 100%

Percent Increase = 44%

Therefore, the percent increase in the area of the fire pit is 44%.beri bintangnya kakak
